The world and everything in it is completely out of our control, vapor of vapors. We experience endless cycles of repetition such that the more things change, the more they stay the same. Cliches are repeated because they are true, and you’ll hear them again. Satisfaction out of man’s reach, but this does not mean it’s out of God’s reach; those who trust and rest in Him receive this gift and rejoice in their labor under the sun. Solomon turns now to consider the inscrutable march of time. We cannot make the crooked straight, but He makes everything beautiful in its time.
