I love the Book of John. It’s the first book I read when I became a follower of Christ. It paints a picture of Jesus in living color. John was not only an eyewitness, he was also part of the inner circle. Jesus regarded John so highly that when He was on the cross, He asked him to take care of his mother. The Book of John also contains a mystery in the following verses:
Many other signs therefore Jesus also performed in the presence of the disciples [after the Resurrection], which are not written in this book; but these have been written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His name (John 20: 30-31 NASB).
And there are also many other things which Jesus did, which if they were written in detail, I suppose that even the world itself would not contain the books which were written (John 21: 25 NASB).
Luke, the only Gentile writer in the New Testament, wrote the Book of Luke and the Book of Acts. (The latter is a continuation of the former.) Luke begins Acts with a passage that illuminates the “mystery” in the Book of John.
The first account I composed, Theophilus, about all that Jesus began to do and teach, until the day when He was taken up, after He had by the Holy Spirit given orders to the apostles whom he had chosen. To these He also presented Himself alive, after His suffering, by many convincing proofs, appearing to them over a period of forty days, speaking of the things concerning the kingdom of God. And gathering them together, He commanded them not to leave Jerusalem, but to wait for what the Father had promised, “Which,” He said, “you heard of from Me; for John baptized with water, but you shall be baptized with the Holy Spirit not many days from now” (Acts 1: 1-5 NASB).
Over forty days! Jesus performed many convincing proofs over a forty day period between His Resurrection and Pentecost. I would love to know what the other “signs” and “convincing proofs” were. But in this season of miracles, I have no doubt that Jesus rose from the dead and offers eternal life to those who repent and accept Him as Lord and Savior.
