Thomas first speaks in the Gospel of John. In John 11:16, when Lazarus has recently died, and the apostles do not wish to go back to Judea, Thomas says: "Let us also go, that we may die with him."[a]
Thomas speaks again in John 14:5. There, Jesus had just explained that he was going away to prepare a heavenly home for his followers, and that one day they would join him there. Thomas reacted by saying, "Lord, we know not whither thou goest; and how can we know the way?"
John 20:24–29 tells how doubting Thomas was skeptical at first when he heard that Jesus had risen from the dead and appeared to the other apostles, saying, "Except I shall see on his hands the print of the nails, and put my finger into the print of the nails, and thrust my hand into his side, I will not believe."[20:25] But when Jesus appeared later and invited Thomas to touch his wounds and behold him, Thomas showed his belief by saying, "My Lord and my God".[20:28] Jesus then said, "Thomas, because thou hast seen me, thou hast believed: blessed [are] they that have not seen, and [yet] have believed
