Throughout the New Testament Jesus tells many parables. But why speak in parables instead of speaking the message directly? The wisdom delivered in these parables seems otherwise impossible to convey.
In the New Testament of the Bible in Matthew Chapter 13, Jesus gives immense knowledge with the parables of the sower, the wheat and the tares, the grain of mustard seed, the leaven, the treasure hid in the field, the pearl of great price, and the net cast into the sea.
These parables seem to connect principle spiritual truths with the temporal world so we can relate to the importance of it all.
When Jesus was asked why he spoke in parables, he answered:
He answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given. For whosoever hath, to him shall be given, and he shall have more abundance: but whosoever hath not, from him shall be taken away even that he hath. Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand. (Matthew 13:11-13)
The knowledge is freely given to everyone, but only those who are seeking it will receive instructions on how to obtain it. These parables contain information about the Kingdom of God and what to do to obtain it.
Additionally, in Jesus’ Sermon on the Mount he says:
Give not that which is holy unto the dogs, neither cast ye your pearls before swine, lest they trample them under their feet, and turn again and rend you. (Matthew 7:6)
My interpretation of this is to not share and give precious things, such as knowledge about Heavenly Father and his Kingdom, that would not be received well to where it would be mocked and may bring harm towards your way.
