…to them, their own opinions are as the word of a god.

A fool takes no pleasure in understanding, but only in expressing his opinion Proverbs 18:2

fools despise wisdom and instruction.

How long, ye simple ones, will ye love simplicity? and the scorners delight in their scorning, and fools hate knowledge?

For the simple are killed by their turning away and the complacency of fools destroys them. Proverbs 1:7b.,29,32.

Whoever trusts in his own mind is a fool Prov.28:6a.

whoever utters slander is a fool. Prov.10:18b.

the mouth of fools feed on folly Prov.15:14b.

the folly of fools is deceiving Prov14:8b.

a babbling fool will come to ruin Prov.10:10b.

the heart of fools proclaim folly Prov12:23b.

The way of the fool is right in his own eyes... Prov12:5a.

the lips of a fool consumes him. The beginning of the words of his mouth is foolishness, and the end of his talk is evil madness Eccles.10:12b.-13.

Christ himself is Wisdom, is Wisdoms. Three sorts of persons are here called by Him: 1. Simple ones. Sinners are fond of their simple notions of good and evil, their simple prejudices against the ways of God, and flatter themselves in their wickedness. 2. Scorners. Proud, jovial people, that make a jest of every thing. Scoffers at religion, that run down every thing sacred and serious. 3. Fools. Those are the worst of fools that hate to be taught, and have a rooted dislike to serious godliness. The precept is plain; Turn you at my reproof. We do not make a right use of reproofs, if we do not turn from evil to that which is good. The promises are very encouraging. Men cannot turn by any power of their own; but God answers, Behold, I will pour out my Spirit unto you. Special grace is needful to sincere conversion. But that grace shall never be denied to any who seek it. The love of Christ, and the promises mingled with his reproofs, surely should have the attention of every one. It may well be asked, how long men mean to proceed in such a perilous path, when the uncertainty of life and the consequences of dying without Christ are considered? Now sinners live at ease, and set sorrow at defiance; but their calamity will come. Now God is ready to hear their prayers; but then they shall cry in vain. Are we yet despisers of wisdom? Let us hearken diligently, and obey the Lord Jesus, that we may enjoy peace of conscience and confidence in God; be free from evil, in life, in death, and for ever.
