25So the other disciples said to him, “We have seen the Lord!” But he said to them, “If I do not see the nail prints in His hands and put my finger into the nail prints, and put my hand into His side, I will not believe!”
26Well after eight days His disciples were inside again, and Thomas with them. The doors were locked again; Jesus came and stood in the middle, and said, “Peace to you!”
27Then He says to Thomas: “Bring your finger here and perceive my hands; bring your hand and put it into my side; do not be unbelieving but believing!”
28Thomas answered and said to Him, “My Lord and my God!”
29Jesus says to him: “Because you have observed me, you have believed. Blessed are those who believe without seeing!”
30Now then, Jesus actually performed many other miraculous signs in the presence of His disciples, that are not written in this book;
31but these have been written so that you may believe that Jesus is the Christ, the Son of God, and that believing you may have Life through His Name.
