Jesus spoke in such a way that only those intent on hearing and learning the truth of His message did, when He spoke in parables those who had ears to hear grasped what His teaching was all about. He knew that the hearts of some had grown callous and their ears were dull of hearing, but when we understand with our heart and repent and are converted His message makes perfect sense(Matthew 13:13-17). Therefore speak I to them in parables: because they seeing see not; and hearing they hear not, neither do they understand. And in them is fulfilled the prophecy of Esaias, which saith, By hearing ye shall hear, and shall not understand; and seeing ye shall see, and shall not perceive: For this people’s heart is waxed gross, and their ears are dull of hearing, and their eyes they have closed; lest at any time they should see with their eyes and hear with their ears, and should understand with their heart, and should be converted, and I should heal them. But blessed are your eyes, for they see: and your ears, for they hear. For verily I say unto you, That many prophets and righteous men have desired to see those things which ye see, and have not seen them; and to hear those things which ye hear, and have not heard them.
The message Jesus brought to the world was never complicated, it was the teachings of the pharisees and sadducees with their traditions which made serving God seem more complicated than it actually is. We must be guarded against traditions that may take us from the truth found only in Christ (Colossians 2:5-9). For though I be absent in the flesh, yet am I with you in the spirit, joying and beholding your order, and the stedfastness of your faith in Christ. As ye have therefore received Christ Jesus the Lord, so walk ye in him: Rooted and built up in him, and stablished in the faith, as ye have been taught, abounding therein with thanksgiving. Beware lest any man spoil you through philosophy and vain deceit, after the tradition of men, after the rudiments of the world, and not after Christ. For in him dwelleth all the fulness of the Godhead bodily.
May we not be beguiled as Eve was through satans subtlity, but stay strong in the word and its truth! (2 Corinthians 11:3).
