A friend of mine and I had a debate this evening about whether or not the apostles were actually believers in Jesus. She claimed that since the Bible does not explicitly say that each man declared belief that Jesus was who he said he was, that one cannot assume that they did believe him. She said that they might have just thought he was doing some "cool stuff" (miracles) and liked what he had to say. She specifically mentioned that Thomas was not a believer until John 20, when he was face to face with the resurrected Jesus. Thomas' statement of "until I see the nail marks...I will never believe" somehow means, to her, that Thomas was never a believer up until he saw Jesus.
My question is this then: is it logical to think that the twelve apostles (also called disciples) were believers in Jesus and his message prior to his crucifixion/resurrection? I am of the belief that since they were selected by Jesus, and considered disciples who followed him everywhere for his 3+ years of ministry and witnessed his execution on the cross, I'd say that they were all believers (even Judas, who committed suicide because of guilt). Thomas decided to not go with the other apostles when they heard that he had resurrected, and when the others told him that Jesus was alive, he didn't believe it. It's not like people rise from the dead all the time; I'd be skeptical too.
Anyway, thoughts? I'm curious to see what the varying denominations believe. (I'm Church of Christ.)
