Some say salvation can be lost, regained, and then lost again. But we can’t grow in the Christian life without the assurance that we’re a child of God. In this message, Pastor Lutzer explores the basis of our ultimate assurance. The testimony of God is greater than testimony of man.

Dave McAllister: Let us run with endurance the race that is set before us. Looking to Jesus, the founder and perfecter of our faith. It's tough to grow in the Christian life without the assurance that you are a child of God. Some say salvation can be lost, regained, and then lost again. Today, why it's crucial to settle the question of knowing you have eternal life. From the Moody Church in Chicago, this is Running to Win with Dr. Erwin Lutzer, whose clear teaching helps us make it across the finish line. Pastor Lutzer, as we talk about the invisible war and being sure we're saved, you'll be telling us about your own early struggles in this area.

Dr. Erwin W. Lutzer: You know, Dave, one of my favorite songs, and of course I have many, is this blessed assurance Jesus is mine. Oh, what a foretaste of glory divine. You're absolutely right. As a boy, I struggled with the issue of assurance. But later on at about the age of 14, I got down on my knees with my parents, and I received Christ by faith as they explained that it isn't really a matter of feeling. Well, the next day I knew that I knew God. And I want everyone who is listening today to have that same sense of assurance thanks to the word of God and the blessed Holy Spirit of God.

I'm so glad for the many of you who support this ministry. Even as I speak to you today, I'm thinking of the Running to Win family. I'd like to give you some information. Would you consider becoming what we call an endurance partner? Of course, you need that info, so here's what you do. Go to rtwoffer.com. That's rtwoffer.com. When you're there, you click on the endurance partner button or call us at 1-888-218-9337. And remember this, God wants you to have the assurance of your salvation. You take my own life. You know, I've told you this story before, but brought up in a Christian home, I used to pray that Jesus would come into my heart.

That was the terminology that we used to use when I was growing up. Every time I got off my knees, I I couldn't uh I didn't feel any different. I didn't feel any witness of the Spirit, so I just assumed I wasn't born of God. It was later at about the age 14 where my parents said, you know, you have to receive Christ by faith even if you don't feel differently, you receive Christ by faith. And I went into the room there with them in the old farmhouse that I got to visit two years ago and knelt there to thank God for all that he had done in my life in the last 50 years.

But as a boy of 14, I knelt and said, in faith I receive Christ now as Savior. And I can tell you that the next morning I so sensed the presence of God so strongly. Now, I'm not saying everyone has this experience. I sensed the presence of God so strongly. I just said to myself, this overwhelming sense of peace and confidence, I know God. I still remember the day when I said, I know God. The ministry of the Spirit. You say, well, what is it like? It's a sense of confidence. It's a sense of awareness.

It's a sense of assurance that you have believed on Jesus. The Spirit, Paul says, bearing witness with my spirit that I am a child of God. And the testimony that I have just given is one that hundreds and hundreds of people who are listening to me today could also give. Oh, you say, but there are people who belong to other religions and they have assurance too. All right, let's take for example my Islam friend that I had in uh in Istanbul. Wonderful man. He took me around all day and showed me archaeological things, very brilliant and a devoted Muslim.

In fact, during the day when he wanted to go into a mosque, I just said, I'll wait outside and and you just pray. I wanted to respect his religion. We should respect people from all different religions. If I were to say to him, are you absolutely convinced that Islam is right? He would say absolutely totally convinced, willing to die that Islam is right. All right. Now, I ask another question. When you die, do you have the assurance that you'll be in heaven? I asked him. No, he said, nobody can have that assurance. We do the best we can and we just hope that Allah will do it, but we have no idea what Allah is going to do.

And I have no idea whether or not I'm going to be there. He's received the testimony of men. And by that I mean the Quran, which is an entirely different subject by the way. But there's no witness of the spirit. There's no inner assurance that he is a child of God. And he has told me that one of the things that is true is they can never refer to God as father. Why? Because it is the spirit that works in the life of those who have believed in Jesus whereby we call God Abba Father. And we know that we belong to him.

Look at the text. I told you it's important to look at the Bible so that you know I'm not making it up. Verse 9, if we receive the testimony of men, the testimony of God is greater. For this is the testimony of God that he is born concerning his son. Whoever believes in the son of God has the testimony in himself. That's a gift of the Spirit. It's the regenerating work of the Spirit confirming the historical record that Jesus is who he claimed to be and that he died for your sins. And if you don't, by the way, John says you make God a liar.

Think about John as he's he's very clear. And he also believes that uh everybody's on one side of the fence or the other. It says in verse 11, and this is the testimony that God gave us eternal life and this life is in his son. Whoever has the son has life. Whoever does not have the son of God does not have life. For John, it was just that clear cut. You either have the son or you don't. If you have the son, you have life. If you don't have the son, you don't have life. Doesn't mean that you can't operate.

You go around and you uh are very much alive, but spiritually disconnected from God. You say, well, Pastor Lutzer, what does all this have to do with the helmet of salvation? Well, it does. You have to hang on because we are going to bring it all together and it's all going to come together if you just keep following me for a few moments. I wish that I had time to comment on the verses that follow. I will read here quickly verse 13. I write these things to you who believe in the name of the son of God that you may know that you have eternal life.

And this is the confidence that we have toward him. We know that he hears us. And then it goes on to talk about a brother who sins a sin unto death. There's some sins that result in death eventually. There are others that don't. You pray for the one, for the other. It may not even be worth praying when you have a case like Ananias and Sapphira. But now notice I'm in verse 18. We know that everyone who has been born of God does not keep on sinning. But he who is born of God protects him.

And the evil one does not touch him. This connects with the helmet of salvation. Now, it says that the one who is born of God does not keep on sinning. In fact, the Greek text, I think actually says he doesn't sin. Well, you and I know that we sin. We sin. If there's a man here who says I do not sin, I would like to meet with his wife and see whether or not she is in hearty agreement. All right? What John is doing in addition to saying that when we are saved, we have a desire to do righteous things and so we don't continue in sin.

It seems to me that John is looking at at us now as being born of God. He's looking at the new nature. When you receive Christ as Savior, there is a new nature within you that cannot sin. That's the struggle as Paul himself said. You know, I have this desire to not sin, and I also have this desire to sin. The new nature certainly doesn't sin. But notice what he says. If we could live without sin, I'm not saying that we do. You'll notice it says that he who is born of God, and I take that he to be the individual Christian, he keeps himself because there is within you now the blessed Holy Spirit of God.

I put it this way that if you are a Christian, you will, I'm sure, sin, but you fight against it and you don't like it because you don't like to displease the Lord. Non-Christians commit sin and they enjoy it and they indulge themselves and they think of new ways of indulging themselves. And there's really no quibble of conscience. We can't sin as Christians without grieving the Spirit. And if we walk with God, we know that we are grieving the Spirit. The Spirit is a person, the spirit that keeps witnessing to us, testifying to us about Jesus.

But you'll notice it says that the wicked one does not touch him. In other words, uh actually the word touch is too weak. It doesn't apprehend him. It doesn't hold him. You see the connection? We talked about the helmet of salvation. When you are walking in obedience and in assurance, the devil comes to you and says, you know, if you are really a Christian, you wouldn't do that. But look at what you're doing. And you say to him, I have the witness of the Spirit. I belong to God. My desire is to follow God. I have sinned, but I confess it and I forsake it and I keep going because at the end of the day I belong to almighty God and not to you, Satan.

Because you have this confidence, this overwhelming sense of saying, I connect with God and I believe in God and his promises. And the Spirit is bearing witness that I am a child of God. Now, how do we put all this together? I'd like to point out to you again, if I may, that it is God's will that you know that you have eternal life. Did you see it there in verse 13? Your Bible is open before you. In verse 13, it says of chapter 5, I write these things to you who believe in the name of the son of God that you may know that you have eternal life.

If you're here today and you don't know that you have eternal life, almost certainly you don't have it. But let me talk very specifically. First of all, to believers. Most believers I've encountered know that they have eternal life. Most of them do. But occasionally you find those that don't. And let me give you some reasons why they lack that assurance, the assurance of the Spirit. And they they genuinely believe sometimes wrong teaching. For example, if you're brought up with the idea that you can just lose your salvation whenever you sin, you're led into such despair that it stifles any ministry of the Holy Spirit to your heart because remember the Holy Spirit is like a dove.

He is gentle. There's a calmness brought to you by the Spirit. It isn't imposed upon you. So if you're taught that you know you're losing your salvation every day, how can the Spirit do any significant witnessing to you if that's what you believe? Or um there are those who sometimes have a weak conscience. If you have a weak conscience so that you see your sin as greater than God's grace, you may have doubts. One day I was speaking at a conference and a husband and his wife asked me to come over to their place because she led Bible study, she led people to Christ, but there were times when she doubted whether she had believed.

Now, I think it is wrong for anyone to say to somebody else, you're a Christian. Let the Spirit do that. But there are times when you're sure that there's no question. They have the fruit of being a Christian. And so I told her, and we are beside a lake, I said, you know, there is a story which I think probably happened of a man who was going to cross a very huge long lake. And he was so afraid that the ice was not thick enough that in places he actually walked on all fours to distribute his weight until in the distance behind him he saw a team of horses coming.

Once he saw the team of horses, oh, get up and walk and enjoy it. If the ice can hold the horses, the ice can hold you too. And I said to her, the ice beneath me and the ice beneath you and the ice beneath all those who have trusted Jesus is thick, equally thick. The only difference is some of us are walking along and we're enjoying it. And you're walking on all fours hoping you won't sink in. The strength of the promises of God. Now, let's suppose you're brought up with a branch of Christendom that says this, that um if you do your part, God does his.

Salvation's a cooperative effort. If you believe that, will you have assurance? Will the Spirit minister assurance? Of course not. First of all, because he ministers to that which is true and not to that which is false. Also that teaching will override any possibility that you can have assurance because if part of it is dependent upon me, I can never be sure that I'm doing my part. But if you believe that when Jesus died on the cross and rose again, he did all that ever will be necessary for you to stand in God's presence and you embrace that for yourself, you will be saved and you will know it and it will be confirmed to you by the ministry of the Holy Spirit.

But there are some Christians who are true Christians, but wrong teaching has kept them from enjoying assurance. Then there are those who walk in disobedience. Now, I'm talking about those who sin and they go against their new nature and they commit sins and they decide to live in sin. Obviously the work of the Spirit. Because the spirit is so sensitive, the spirit will be grieved and there'll be no ministry of assurance to a person like that. But God wants you to know these things. And I take it to be just the preceding verses, these things I have written on to you that ye may know that you have eternal life.

So much for those who believe. Now, for many of you who are listening who have no assurance whatever, it's possible that the real reason is because you have not really believed on Jesus. I remember a teenager saying to me, the teenager said, you know, I received Jesus as my Savior in the youth meeting, but I can't tell my parents because my parents always tell me that I was saved because I prayed a prayer at the age of 5. Could I say that it's possible for you to pray even a good prayer and not be saved?

Because it isn't even prayer that saves us. It is that transfer of trust where we believe into Jesus and we trust him. The full weight of our sin and our future is laid on him. That's what it means to believe in Jesus as being the Christ. And then we'll be born of God. So you see there are those who have a false sense of assurance because uh they have never really savingly believed. There are those who are so self-assured that even when they listen to a message like this, it's filtered. And their filter tells them that what he's really trying to say is that salvation is a matter of just being good.

So they keep believing that and they develop their own sense of self-confidence. But when push comes to shove, there's no assurance because they've never believed. How do I illustrate this? Think of O'Hare Airport. You're there in the departure lounge. Have you ever noticed the difference between those who have a confirmed ticket and those who are flying standby? And I've been in both categories. When you have a confirmed ticket, you're sitting there reading the newspaper, you're dozing, you're laughing and joking with your friends. And you're enjoying the weight. When you're flying standby and they tell you, well, we have no seats, but it's possible that someone won't show.

What are you doing then? You're pacing the floor, you're looking down on the floor, you're rolling your eyes, you're trying to listen to what's being said. You keep your eye on the monitor and there you are. You know, you're unsure. When you believe in Jesus as the Savior, as the one who bore your sin, who came both by water and by blood, you receive the ministry of the Spirit that confirms that you've got a ticket, confirmed ticket, and you don't have to worry about the departure lounge. James Simpson, who was the first to use chloroform in medicine, was dying.

People said to him, what is your speculation regarding your future? It's a question to ask somebody who's dying. He said, I have no speculation. And then he said this, quoting right from the Bible. I know whom I have believed and am persuaded that he is able to keep that which I have committed unto him against that day. That is the confidence of all those who trust Jesus as Savior, who have who are born again, born of God, who now love God because they're born of God. And the spirit witnesses to them that their ticket has been confirmed.

And they're good to go all the way to heaven. So do you have assurance? Do you know that you have eternal life? Has your ticket been confirmed? Or are you flying standby? Let's pray. Father, I pray that you might help us to pick up the shield of salvation or I should say the helmet of salvation. And I pray that your Holy Spirit may point out in the lives of all those who are here who have never really trusted Christ as Savior, who are flying standby, that they can have a confirmed ticket. Father, I ask in the name of Jesus that all those who lack assurance today may believe in Christ so fully that your spirit will minister to them and they will know that they belong to you forever.

In Jesus' name we pray. Amen. Amen.

Dr. Erwin W. Lutzer: Well, this is Pastor Lutzer and I have two questions for you. Number one, do you have assurance of salvation? Are you sure thanks to the promises of God and the witness of the Spirit of God? If not, would you repent and believe on Christ right now? The second question I have for those of you who do have assurance. Do you rejoice in the fact that messages like this are being sent around the world through the ministry of Running to Win? If you say yes to that, it's because people just like you have supported this ministry, you have invested in it.

And I'm going to ask you to pray and to think about the possibility of becoming what we call an endurance partner. I'm holding in my hands a letter from a Russian listener who says, when you spoke to issues such as marriage and relationships in the family, it just exploded in my life. My whole family too can testify how God worked in our hearts helping us. And you know, my friend, the reason that I can read a letter like this is because, yes, indeed Running to Win is in Russian. It's also in many other languages. Why?

As I've already emphasized, it's because of people just like you. Would you consider becoming an endurance partner? Would you ask the Lord if you would become a part of what I like to call the Running to Win family? Well, I sure hope that you have a pen or pencil handy because this is what you can do.
