When I grew up, many times I would hear someone tell something and someone else would respond, “That doesn’t sound right,” and they would call the person “Doubting Thomas.”
I grew up with “Doubting Thomas,” not knowing it came from the Bible. I believe a lot of people who would use this saying did not know it came from the Bible either.
In John 14, Jesus told his disciples that he was going away to prepare a place for them and where he was there they could be, also.
