Why did jesús preach using parables

The Lord Jesus frequently used parables as a means of illustrating profound, divine truths. Stories such as these are easily remembered, the characters bold, and the symbolism rich in meaning. Parables were a common form of teaching in Judaism. Before a certain point in His ministry, Jesus had employed many graphic analogies using common things that would be familiar to everyone (salt, bread, sheep, etc.) and their meaning was fairly clear in the context of His teaching. Parables required more explanation, and at one point in His ministry, Jesus began to teach using parables exclusively.
