Here John inserts his commentary: "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" (John 20:30-31).
John wrote his account of Jesus' life so that we, who have not seen Jesus, who have not witnessed his miracles, who have not touched his wounds, might believe, and in believing gain eternal life.
For reflection: Jesus said to Thomas, "Stop doubting and believe." What is my answer? Knowing what befell Jesus and what would happen to his disciples because of this belief, where do I stand?
With Thomas, let us pray: My Lord and my God!
