John 20:29

²⁷ Then Jesus said to Thomas, “Put your finger here and look at My hands. Reach out your hand and put it into My side. Stop doubting and believe.”

²⁸ Thomas replied, “My Lord and my God!”

Jesus said to him, “Because you have seen Me, you have believed; blessed are those who have not seen and yet have believed.”

³⁰ Jesus performed many other signs in the presence of His disciples, which are not written in this book.

³¹ But these are written so that you may believe that Jesus is the Christ, the Son of God, and that by believing you may have life in His name.

Do read the surrounding verses too, because the context often says more than a single verse.
