John 20:24-25

24One of the 12 disciples was called Thomas. (He was also called ‘the Twin’.) He was not with the other disciples when Jesus came to them.

25So the other disciples told him, ‘We have seen the Lord.’ But Thomas said to them, ‘I will never believe that he is alive again unless I myself see him. I want to see the marks of the nails in his hands. I want to touch where the nails were with my finger. I want to put my hand into his side where the spear went in. If I cannot do that, I will not believe.’
