The first twenty chapters of St. John’s Gospel account are about erasing any doubt that Jesus is truly God. The twenty-first chapter is an encore, and its focus is on preparing Christians to let it be known in the world that Jesus is our God, our brother and our Savior.
The Christian God is not a God of moral excellence, rather He is a God of moral perfection. Since we are unable to be perfect as our Father in heaven is perfect, we need a Savior. And have a Savior we do. He is none other than God Himself in the flesh, Who lived a life without sin and died in our place as our substitute under God’s perfect justice. Let there be no doubt! Let us proclaim as Thomas did, “My Lord and my God.”
