Psalm 7:12-16 (The Message)

Nobody gets by with anything. God is already in action— Sword honed on his whetstone, bow strung, arrow on the string, Lethal weapons in hand, each arrow a flaming missile. Look at that guy! He had sex with sin, he's pregnant with evil. Oh, look! He's having the baby—a Lie-Baby! See that man shoveling day after day, digging, then concealing, his man-trap down that lonely stretch of road? Go back and look again—you'll see him in it headfirst, legs waving in the breeze. That's what happens: mischief backfires; violence boomerangs.

David is confident that he shall find God his powerful Saviour. The destruction of sinners may be prevented by their conversion; for it is threatened, If he turn not from his evil way, let him expect it will be his ruin. But amidst the threatenings of wrath, we have a gracious offer of mercy. God gives sinners warning of their danger, and space to repent, and prevent it. He is slow to punish, and long-suffering to us-ward, not willing that any should perish. The man is described as taking more pains to ruin his soul than, if directed aright, would save it. This is true, in a sense, of all sinners. Let us look to the Saviour under all our trials. (Matthew Henry's)

Galatians 6:7-8 (Amplified Bible)
Do not be deceived and deluded and misled; God will not allow Himself to be sneered at (scorned, disdained, or mocked by mere pretensions or professions, or by His precepts being set aside.) He inevitably deludes himself who attempts to delude God. For whatever a man sows, that and that only is what he will reap. For he who sows to his own flesh (lower nature, sensuality) will from the flesh reap decay and ruin and destruction, but he who sows to the Spirit will from the Spirit reap eternal life.
