As you do not know the way the spirit comes to the bones in the womb of a woman with child, so you do not know the work of God who makes everything.
In the morning sow your seed, and at evening withhold not your hand, for you do not know which will prosper, this or that, or whether both alike will be good.
So if a person lives many years, let him rejoice in them all; but let him remember that the days of darkness will be many. All that comes is vanity.
Rejoice, O young man, in your youth, and let your heart cheer you in the days of your youth. Walk in the ways of your heart and the sight of your eyes. But know that for all these things God will bring you into judgment.
