Proverbs 28:26 He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered.
The promises in Proverbs often come in contrasts: wise and fool, black and white, good and evil, all contrasting believer and unbeliever. The fool (the unbeliever) trusts in himself, in his own opinions, thoughts, and ideas. He does not realize how darkened, empty and stupid his soul has become after the Fall. James says that wisdom not from above is “earthly, unspiritual, demonic.”
The fool says there is no God. The practical atheist ignores God and acts as if He isn’t really involved. The wise fear, love, and trust in God above all things. The contrast is clear. The outcomes are clearer.
The promise of deliverance, solutions for problems, comes to those who “walk wisely,” that is, believers who trust God, believe His Word, and live according to it. This we pray for in the Lord’s Prayer. We are delivered from the evil we got ourselves into. Life has been described as a series of solving problems. This life God gives us through Christ. We shall be delivered!
