Deut 29:4.   Yet the LORD hath not given you an heart to perceive, and eyes to see, and ears to hear, unto this day. Mark 4:11-12.   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.
