Please read your bible before asking questions that are already answered in the bible. Yes, the bible does explain why it is written in confusing parables. Grab your bible and lookup Mark 4:11-12. Or I quote it following:
Quote:
"And he said unto them, Unto you it is given to know the mystery of the kingdom of God: but unto them that are without, all these things are done in parables: That seeing they may see, and not perceive; and hearing they may hear, and not understand; lest at any time they should be converted, and their sins should be forgiven them."
(Jesus according to Mark 4:11-12, KJV)
As Jesus himself explains above, the reason why he talks in parables is to confuse people so that they will go to hell (not be forgiven). Yes I know that is sadistic, but if you had actually read your bible you would already know that Jesus is sadistic.
