Ecclesiastes states that people should enjoy themselves and the fruits of their labors. This too is meaningless. This too is meaningless, a chasing after the wind. Even if a wise man claims he knows, he cannot really comprehend it.
Wisdom is better than weapons of war, but one sinner destroys much good.
As you do not know the path of the wind, or how the body is formed in a mother's womb, so you cannot understand the work of God, the Maker of all things. For God will bring every deed into judgment, including every hidden thing, whether it is good or evil.
