"but these [signs] 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 20:31

So here's the challenge: read the book of John. It is only 21 chapters long. I've gone through it in about a week, moving through it at a moderate pace as I read through other books during my devotion/study time also. Devote a week or two to reading a chapter or two a day of the Gospel of John. Why? Because John states his purpose for writing the gospel in the verse above.

The whole reason, the mission statement for his writing the gospel that we now call the book of John was so that people would believe in Jesus, believe that he is the Christ, the Messiah, the Savior of the world, who is the Son of God, and, that in so believing, we would have life that comes only through his name. Jesus said so much concerning these things that John recorded: "For God so loved the world that he sent his only Son" (3:16); "Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God" (3:18); "Whoever believes in the Son has eternal life" (3:36); "I say these things that you may be saved" (5:34); "the dead will hear the voice of the Son of God, and those who hear will live" (5:25); "This is the work of God, that you believe in him whom he has sent" (6:29); "whoever believes has eternal life" (6:47); The disciples speaking to Jesus, "Lord, to whom shall we go? You have the words of eternal life" (6:68).

That list above is small, far from being exhaustive. I dare you to read the book of John. Believer or unbeliever. I don't care. Read it. And believe more than you currently do. That's why it was written. If you don't believe in God, then what will it hurt to read some good, ancient literature? It won't, so try it out, see what happens. If you are a follower of Jesus Christ, make sure to strengthen your faith by reading the book of John.

May the Lord reveal Himself to us all through the person and work of His Son, Jesus Christ, through the reading, preaching, and study of His Holy Scriptures. Amen.
