Matthew 13:35

that it might be fulfilled which was spoken by the prophet, saying, I will open My mouth in parables, I will utter things which have been kept secret from the foundation of the world.

It was at this time that Jesus made use of this form of teaching for reasons which Matthew had indicated above, v. 13. Here again was a prophecy fulfilled, Psalms 78:2. But, though the majority of the audience no longer had the true spiritual benefit from the beautiful stories which Jesus told them, yet there were a few that would understand His language. For them His teaching became in reality a revealing, a making known, of the wonderful things of God which had been hidden since the foundation of the world, known only within God's council. The invisible, heavenly beauties are here unfolded before the eyes of the unlearned disciples in a simple, appealing manner, though Christ was obliged, especially at first, to open the eyes of their understanding.
