> Well yes, to people who don't believe it is simply a story. Just like everything else in the bible.
If one has strong belief, one doesn't need XXX to part the valley of water. He can do it himself.
Is XXX = God?
Well if one has strong belief, it is not in himself, it's in the one who gives him the ability to part the water or do such miracles.
In other words, it's not man's own aptitude that allows him to do this... it is God's power through him.
