Jesus did many other miraculous signs in the presence of his disciples, which are not recorded in this book. But these are written that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in his name.
Why was the Gospel of John written? The author tells us why in the verses that close chapter 20. John is saying that there were many other things about which he could have written but that the things he did write were chosen rigorously on the basis of a two-part goal. That goal centers in a person, the Lord Jesus Christ. The first part, the chief, is that those learning about Jesus might believe that he is the Christ, the Son ofGod. The second part, a consequence of the first, is that the one believing might have eternal life through Christ’s name. If we look at all of John’s Gospel on the basis of the above, we can note that John’s Gospel is a series of witnesses to Christ. I come now to the final and most important question: If John’s purpose and the purpose of the Holy Spirit who inspired his writing is to lead men and women to faith in Jesus as the Son of God and Savior, shall that purpose fail where you personally are concerned? Do you believe? You have undoubtedly known of Christ and his work for many years. You may even have followed these studies of John’s Gospel over a long period of time. What a tragedy it would be to come to the end of such a study and fail to enter into eternal life through faith in Jesus yourself. Do not allow that to happen. Believe on him. Believe now.
