Your analogy fails.#2 to claim that Jesus was not all powerful because of Mark 6:5 is to not even have read the passage.
"But Jesus, said unto them, A prophet is not without honour, but in his own country, and among his own kin, and in his own house.
5 And he could there do no mighty work, save that he laid his hands upon a few sick folk, and healed them."
in life what we can do and what we can not bring ourselves to do are often the same thing. as a track coach i can find ways to cheat. but because i am an honest person and the bigger picture is more important than the opportunity of the moment i could not [choose not to] cheat. just because it says that he couldn't do it does not mean that it was not in his power to do so rather because of circumstances he chose not to.
Jesus was, according to you-- a GOD.
He either is a god, or he's a fake.
If he's a god? He has unlimited power--right there on the label.
If his power is limited?
He's not a god.
