Ecclesiastes 3:10-15 - No One Understands God's Mysterious Plan

¹⁰ I have seen the task, which God has given to the sons of men to be occupied in it. ¹¹ He has made every thing beautiful in its time: also he has put eternity in men's hearts, so that no man can find out the work that God does from the beginning to the end. ¹² I know that there is no good in them, but for a man to rejoice, and to do good in his life. ¹³ And also that every man should eat and drink, and enjoy the good of all his labor, it is the gift of God. ¹⁴ I know that, whatsoever God does, it shall be forever: nothing can be added to it, nor any thing taken from it: and God does it, that men should fear before him. ¹⁵ That which has been is now; and that which is to be has already been; and God requires that which is past.
