Why John Wrote
30Now Jesus did many other signs in the presence of the disciples, which are not written in this book;31but these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name. —John 20:30-31
I believe if you want to write a letter to somebody, you should be able to determine what the letter is about. If I want to preach a sermon, as long as it’s from God's Word, I should be able to decide what the sermon is about. And the recipients of the letter or audience of the sermon ought to know that purpose. I don’t want to go to a church where the preacher doesn’t even know what the sermon is about.
In John 20:30-31, John tells us what his book is about. You don’t have to wonder. In fact, John’s gospel is transparent from start to finish about Who and what the main subject is—Jesus Christ.
John writes in John 20:30, “Now Jesus did many other signs in the presence of the disciples (And John was one of them. John saw what He did.),which are not written in this book.” In another place, John says, “Now there are also many other things that Jesus did. Were every one of them to be written, I suppose that the world itself could not contain the books that would be written” (John 21:25). We won’t know everything Jesus did until we get to heaven.
But you might be wondering, Well, how did he choose what to include?
“But these are written(I chose my material) so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name” (v.31). John uses believe ninety-seven times in his gospel. I always tell a new believer, “If you’re new in your faith, start reading the Gospel of John every day and underline the word believe.
What am I supposed believe?
John is saying, I wrote this stuff so you may believe Jesus is the Christ, the Promised One, the Messiah.
What will happen if I believe that?
“By believing, you may have life in His name.”Life is another common word in John’s gospel. About half of the references are to eternal life; half are to abundant life here and now. Jesus said, “I came that they may have life and have it abundantly” (John 10:10).Jesus wants you to have the life you were created to experience—not just the promise of eternal life, but abundant, fulfilling life here and now. —James MacDonald
· How would someone observing me closely see I’m living an abundant life in Christ?
· What distorts and distracts from Christ’s presence in my life?
Father in heaven, thank You for the gifts of eternal and abundant life! Help me to live out the reality of Your presence in me today, even as I enjoy the hope of a life beyond this one on a plane I can hardly imagine. Thank You for keeping me grounded in what You want me to be doing today even as I anticipate the arrival of Your Day! Guide me in pursuing every aspect of Your amazing gift of life as I go about my day today. In Jesus’ life-giving name, Amen.
