John 20:24

But Thomas, one of the twelve, called Didymus, was not with them.

Didymus, which means the Twin, is the Greek for the Hebrew name, Thomas. He was one of the Twelve, of whom history has recorded but little. It is reported by tradition that he carried the gospel to India and died there. He seems to have been an honest, affectionate man, but of. rather skeptical turn of mind. This incident, as well as the unbelief of the others prior to the meeting of the Savior with the apostles, shows that they were very incredulous, and hard to convince, notwithstanding the Lord had said he would rise again. Only "infallible proofs" could convince them. The failure of Thomas to be present with the other disciples was probably due to his utter despair.
