Those Young Earth Creationists who say they will not believe Christ if there is not physical proof that the universe is only 6000 years old are like doubting Thomas.
But doubting Thomas was an apostle, too.
Physical proofs certainly have their limitations. It depends upon what one is trying to prove. It also depends upon one's perception of the proof.
It seems to me that Thomas was seeking to know rather than believe. IMO his error was in seeking knowledge from without rather than from within. Though he may have attained that inner knowing from that experience it should not be ignored where his change of view took place. I don't think it happened in his fingers. ; )
But doubting Thomas was an apostle, too.
Yes he was and it's too bad that the Gospel of Thomas is held in such disregard. It holds some very knowing statements.
