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

¹⁰ I have seen the travail that God hath given to the sons of men to toil in. ¹¹ He hath made everything beautiful in its time; also he hath set the world in their heart, so that man findeth not out from the beginning to the end the work that God doeth. ¹² I know that there is nothing good for them but to rejoice and to do well in their life; ¹³ yea also that every man should eat and drink, and enjoy good in all his labour, it is the gift of God. ¹⁴ I know that whatever God doeth, it shall be for ever; there is nothing to be added to it, nor anything to be taken from it; and God doeth it, that men should fear before him. ¹⁵ That which is was long ago, and that which is to be hath already been; and God bringeth back again that which is past.
