A Doubting Thomas

A site visitor wrote the following reguarding this idiom:
This saying originated from the Bible. It is the story about when Jesus returns (after his crucifixion) and visits his disciples (Joh 20:19). All of the disciples are there except Thomas (Joh 20:24). When the others tell Thomas that they had seen Jesus he doesn't believe them and makes the comment, (Joh 20:25) "But he said unto them, Except I shall see in 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. Then Jesus makes a believer out of him when he returns eight days later and sees Thomas and says, (Joh 20:27) Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing. (Joh 20:28) And Thomas answered and said unto him, My Lord and my God.
