Proverbs 12:23 A prudent man conceals knowledge: but the heart of fools proclaims foolishness.
‘A prudent man conceals knowledge: but the heart of fools proclaims foolishness.’ A wise man never brags about his education, knowledge, or experience, but a fool tells everybody how wise he is. The wisdom of this world is a craft, or subtle trade, which people carry on with others to benefit themselves.
The wise of the world is always full of schemes and plans for earthly gain, all of which are empty and vain. The natural man is the man living under the control of the fleshly passions, the sensual and depraved part of man in contrast with the rational part (Gal. 5:19-21; Rom. 1:29-32; 1Cor. 6:9-11; Col. 3:5-10). He has no sense of spiritual values and no relish for them. He counts it the highest wisdom to live for this world and carnal pleasures. Spiritual things are foolishness to him. He cannot see their supreme excellence due to animal appetites and being spiritually dead (Eph. 2:1-9).
