25The other disciples therefore said to him, “We have seen the Lord!” But he said to them, “Unless I see in his hands the print of the nails, put my finger into the print of the nails, and put my hand into his side, I will not believe.”
26After eight days, again his disciples were inside and Thomas was with them. Jesus came, the doors being locked, and stood in the middle, and said, “Peace be to you.”
27Then he said to Thomas, “Reach here your finger, and see my hands. Reach here your hand, and put it into my side. Don’t be unbelieving, but believing.”
28Thomas answered him, “My Lord and my God!”
29Jesus said to him, “Because you have seen me, you have believed. Blessed are those who have not seen and have believed.”
30Therefore Jesus did many other signs in the presence of his disciples, which are not written in this book;
31but these are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in his name.
