How to Change

July 26, 2024

Through faith in Christ, through the gospel, through the Holy Spirit, you can experience lasting, deep, radical, permanent change.

If you’re going to make such changes, you need to understand the nature of Christian change. You have to understand the nature of it, the pattern of it, and the process of it.

Galatians 5 shows us that Christian change is 1) gradual, 2) inevitable, 3) internal, and 4) symmetrical.

This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on April 19, 1998. Series: Galatians: New Freedom, New Family. Scripture: Galatians 5:16-18,22-25.

When you become a Christian, the same power that raised Jesus from the dead comes into you spiritually, internally. You have the power to change. You have an unsurpassed power to change. So we have to ask ourselves right away, “Are we settling for too little?” I mean, how much have you changed so far? The power that raised Jesus from the dead, that broke the bands of death, is in you. Now, how does it actually work? Let’s look at 1) the signs of spiritual deadness, 2) the signs of spiritual life, and 3) how you move over from death to life. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on April 12, 1998. Series: Galatians: New Freedom, New Family. Scripture: Galatians 5:13-25.

Freedom is the greatest value in the modern Western world. The secular model of freedom is basically freedom from something. It says, “I am only free when there’s nothing in my way.” When people come to Christianity, they would like inspiration and help, but they don’t want to give up their freedom. Very often, Christians say to them, “You must give it up. God has a will,” but the Bible doesn’t come at it like that at all. The Bible instead is dripping with the language of freedom. So let’s look at what this text shows us about 1) the failure of secular freedom, and 2) the nature of real Christian freedom. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on April 5, 1998. Series: Galatians: New Freedom, New Family. Scripture: Galatians 5:5-18.

How could the idea that you’re saved by grace alone be any incentive to live a good life? Paul says the gospel of salvation through free grace, not works, is actually a greater incentive to a life of honesty, sacrifice, and love than anything else. He’s talking about how we change the human heart, and he says the motivation behind what we do is all-important. Paul tells us 1) what the new motivation is, and 2) how the new motivation works. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on March 29, 1998. Series: Galatians: New Freedom, New Family. Scripture: Galatians 5:5-12.

Most people think the job of religion is to call people into a life of morality. But Paul says that’s not what Christianity is at all.Gospel transformation is completely different than moral reformation. In Galatians 5, Paul says there are two different reasons you could obey God—and the reason for your obedience makes all the difference in the world.Paul tells us 1) there is a wrong reason for moral obedience, and it enslaves us, and 2) there is a whole other engine for obedience, and it is hope and love.This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on March 22, 1998.

What’s the purpose of writing a letter to somebody? The purpose is to get something across. So when we read the Bible, we need to have the intellectual integrity to treat it the way we’d want our own communications treated. Galatians 4 is a text that many find difficult to read and interpret. What is Paul saying? What does he mean? But if we understand the context, it really is very simple in the end. If we look at Galatians 4, we’ll see 1) he talks about two sons, 2) then he talks about two covenants, and 3) then he gives two applications. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on March 15, 1998. Series: Galatians: New Freedom, New Family. Scripture: Galatians 4:21-31.

The difference between a sword and a scalpel at first sight doesn’t seem that great. But you can either cut in order to defeat or in order to heal. The book of Galatians is counseling, and for Paul, truth is a scalpel. He’s not using truth to bludgeon, but to do surgery. And the reason this truth changed other people’s lives was because Paul brought the truth through the mode and channel of true friendship. We’re told three things in this passage about transforming friendships: 1) a friend has a vision for who God is making you, 2) a friend has a vision for Christ being formed in you, and 3) a friend is willing to go into labor pains for it all. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on March 8, 1998. Series: Galatians: New Freedom, New Family. Scripture: Galatians 4:21-31.

If you want to be an agent of reconciliation and change and healing in the lives of others, Paul says something that applies to us all. Paul says the essence of his ministry was this: “become like me, for I became like you.” There are two sides to that sentence. Only by the power of God can you do both. But if you can do both, you can change people’s lives. Here’s what you need: 1) you need ministers, 2) you need the kind of ministers who understand the gospel, and 3) you need ministers who labor until Christ is formed in you. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on March 1, 1998. Series: Galatians: New Freedom, New Family. Scripture: Galatians 4:12-20.

This is a startling passage. The context is that the Galatians, who became Christians out of pagan backgrounds, are now falling under the influence of teachers who say, “It’s not enough just to believe in Jesus Christ. You also have to obey everything in the Bible.” Paul says something here which is astounding. He says that if they do that, they will fall back under what he calls the slavery of the non-gods. So we ask ourselves three questions: 1) what are the non-gods? 2) how do they enslave? and 3) how can we be free? This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on February 22, 1998. Series: Galatians: New Freedom, New Family. Scripture: Galatians 4:8-20.

As a new Christian, I thought of salvation as taking things off of me: that my sins were taken off. But at the very same moment, there’s another part of that legal transaction: something is put on me. I’m adopted as God’s own son. Galatians tells us that because we’re legally adopted, we have an agent—it’s the Spirit. The Spirit is sent not into the world but into our hearts. And the Spirit comes to give not the objective status, which we already have, but the subjective experience of sonship. Let’s break it into three things: 1) what is promised, 2) what it’s like, and 3) how it comes. This sermon was preached by Dr. Timothy Keller at Redeemer Presbyterian Church on February 8, 1998.
