Ah and then we get to the whole idea of the apostles "adding the words of Christ that He said He was the messiah." If this were to be true, don't you think all this whole farce would've fallen through after a few years, or maybe decades, because there would've been no power behind the name of Jesus afterall? Why would these guys have done this? They were all taken from their various jobs and former lives because they were attracted to this man, Jesus. He said for them to "Follow Me," and they did. During that time, they learned many things and other things, they didn't understand at all. Mostly, they were amazed at Him and attracted to who He was. If someone were to raise dead people back to life and multiply small amounts of fish into enough to feed 5000 and walk on water and then, be crucified publicly so that his closest friends were terrified to go anywhere or be affiliated with him......and then for this person to appear alive afterwards.....wouldn't you be convinced He was the messiah? It's funny, because they didn't! They were scared to death, but waited, as Jesus told them to, for "the Comforter to come." It wasn't until the Holy Spirit came after Jesus ascended back to Heaven that the disciples began to move in power and boldness to spread the word about Jesus.
What is also interesting is that if Jesus was just a great teacher, that would be it. No resurrection from the dead, because great teachers just don't have that power. I can't recount all the times I've heard people, today, during my lifetime, tell how Jesus has changed their lives in major ways. A great teacher might have some good hints for you to improve your way of thinking for a limited time ("I'll help this person today, because I remember reading this great man, Jesus, helped people.."), but that would be the extent of it. But when I see a person who's been addicted to drugs or pornography be prayed for consistently by family and friends in the name of Jesus be transformed and set free, that's a different story. Their countenance changed, a hope and joy is present, where depression and anger formerly were, and nothing is the same.....and sometimes, they end up dedicating their life to ministering to the prostitutes in another country. A great teacher's old words can't produce that kind of change.
Of course, all that could just be a sham and the whole thing is a big lie concocted by 12 men who were set out on pulling a big one over the whole world.
