Ecclesiastes 7:14

In the day of prosperity be joyful, enjoying God's blessings with due thankfulness, but in the day of adversity consider, regard most carefully, let your thoughts run along these lines; God also hath set the one over against the other, He sends evil days as well as good, to the end that man should find nothing after him, in order that the future be hidden and remain hidden from man, for if the veil were lifted which hides the future, men would consider themselves independent of the divine dispensation.
