Christ didn't decieve anybody. He spoke in parables. Why did he do that?
And the disciples came, and said unto him, Why speakest thou unto them in parables? 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. And in them is fulfilled the prophecy of Isaiah, 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. (Matthew 13:10-15 KJV)
Have you now rejected free will?
Where in the Bible does it teach that man has a "free" will?
Man's will, like everything else in the universe, is subject to God's will. If God chooses to open one man's eyes and leave another man blind, who are you to complain? Obviously by speaking in parables, Christ chose not to reveal his truths to some people while revealing those truths to those whom he had chosen to be his disciples.
Well he's God... and we're not.
Christ spoke in parables to call us our of our slumber, see in Matthew 13 how the hearts, ears and eyes have become unable to bear the word of God plainly, as we do a news report, the parables are not hard to understand ( sometimes with a little help) for those with ears to hear but for the deaf and blind and awaking of faith, an acceptance of the gift of grace is needed, saying "yes" to grace takes many forms. If the parables are perfectly understandable to the chosen, why do they need pastors, bible studies, commentaries, concordances etc? It's because He is giving us a chance to say "yes" at the most basic level, I want to understand, help me understand Lord! This is another reason He gave us a Church before He gave us the canon of Scripture. The heirs of the apostles help any today who want to hear and see.
