Thomas said to him, “My Lord and my God!”

Thomas proves to be much less skeptical than he thought. When he sees Jesus and hears His words to him, Thomas’ doubts all vanish and he believes without applying any of the tests he had previously demanded. (It seems certain that Thomas did not put his finger in the nail prints or the side of Jesus because Jesus states in the next verse (20:29) that he believed because he had “seen.”)

John 20:29  Then Jesus told him, “Because you have seen me, you have believed; blessed are those who have not seen and yet have believed.”

The reluctance of Thomas to believe in the resurrection of Christ is a benefit to our own faith because it proves that those who were witnesses of the resurrection were not easily fooled, but were cautious men, inspecting all of the data before jumping to any conclusions.

Thomas may have been slow in accepting the resurrection of Christ, but when he did, he went all the way. He declares Jesus to be not only his Lord, but also his God. This was a tremendous leap of faith! Nobody had ever called Jesus by this latter designation. Thomas intuitively saw that Jesus had to be God because no mere man could ever raise himself from the dead.

Many scholars think that chapter 21 is an appendix that was added later and that chapter 20 was originally the close of John’s gospel. Whether true or not, this statement of Thomas certainly makes a fitting conclusion to the gospel that started with the declaration that “the Word was God.” (John 1:1)

John 1:1  In the beginning was the Word, and the Word was with God, and the Word was God.

Thomas’s statement is quite similar to the reversed address to God in (Psa 35:23). Jesus is not just “a” lord but He is the one Lord (1 Cor 8:6, 1 Tim 2:5, Act 2:36, Rom 14:9, Php 2:9-10) and He is God (John 1:1, 1:18, Acts 20:28, Rom 9:5, Titus 2:13, Heb 1:8, Php 2:5-7, Matt 1:21-23, 4:7).

John 1:1  In the beginning was the Word, and the Word was with God, and the Word was God.

John 1:18  No-one has ever seen God, but God the One and Only, who is at the Father’s side, has made him known.

Matthew 1:21-23  She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins.”  All this took place to fulfil what the Lord had said through the prophet:  “The virgin will be with child and will give birth to a son, and they will call him Immanuel”— which means, “God with us.”

Matthew 4:7  Jesus answered him, “It is also written: ‘Do not put the Lord your God to the test.’”
