But Thomas, one of the twelve, called Didymus, was not with them when Jesus came. The other disciples therefore said unto him, We have seen the Lord. 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.—John 20:24, 25.
I OFTEN think that Thomas was the most unhappy man in Jerusalem during the week that followed. It would have been far more reasonable for him to have believed those who saw Jesus, rather than to have doubted their word. But unbelief is the most unreasonable thing in the world.
