Ecclesiastes 11:7KJV

5As thou knowest not what the way of the spirit, how the bones in the womb of her that is with child: even so thou knowest not the works of God who maketh all.

6In the morning sow thy seed, and in the evening withhold not thine hand: for thou knowest not whether shall prosper, either this or that, or whether they both alike good.

7Truly the light sweet, and a pleasant for the eyes to behold the sun:

8But if a man live many years, rejoice in them all; yet let him remember the days of darkness; for they shall be many. All that cometh vanity.

9Rejoice, O young man, in thy youth; and let thy heart cheer thee in the days of thy youth, and walk in the ways of thine heart, and in the sight of thine eyes: but know thou, that for all these God will bring thee into judgment.
