Gods Word says.....
"Having eyes, see ye not? and having ears, hear ye not? and do ye not remember?" (Mark 8:18)
"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." (Matt 13:13-15)
"Hear now this, O foolish people, and without understanding; which have eyes, and see not; which have ears, and hear not: Fear ye not me? saith the LORD: will ye not tremble at my presence, which have placed the sand for the bound of the sea by a perpetual decree, that it cannot pass it: and though the waves thereof toss themselves, yet can they not prevail; though they roar, yet can they not pass over it? But this people hath a revolting and a rebellious heart; they are revolted and gone. Neither say they in their heart, Let us now fear the LORD our God, that gives rain, both the former and the latter, in his season: he reserves unto us the appointed weeks of the harvest. Your iniquities have turned away these things, and your sins have with held good things from you. For among my people are found wicked men: they lay wait, as he that set snares; they set a trap, they catch men. As a cage is full of birds, so are their houses full of deceit: therefore they are become great, and waxen rich. They are waxen fat, they shine: yea, they overpass the deeds of the wicked: they judge not the cause, the cause of the fatherless, yet they prosper; and the right of the needy do they not judge. Shall I not visit for these things? saith the LORD: shall not my soul be avenged on such a nation as this? A wonderful and horrible thing is committed in the land; The prophets prophesy falsely, and the priests bear rule by their means; and my people love to have it so: and what will ye do in the end thereof?" (Jer 5:21-31)
