 We could all have doubts, but Thomas didn't just give in to his doubts. He persevered through them. And we all have different needs, and the Lord meets us where we're at. And I'm sure that St. Thomas was really hurting. Maybe that's the reason why he wasn't around with the rest of the apostles. He was so grief-stricken that our Lord had died on the cross, and it took him a week to come around.
