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

10 For as touching the travail and carefulness which God hath given unto men, I see that he hath given it them, to be exercised in it. 11 All this hath he ordained marvelous goodly, to every thing his due time. He hath planted ignorance also in the hearts of men, that they should not find out the ground of his works, which he doth from the beginning to the end. 12 So I perceived, that in these things there is nothing better for a man, then to be merry and to do well so long as he liveth. 13 For all that a man eateth and drinketh, yea whatsoever a man enjoyeth of all his labor, the same is a gift of God. 14 I considered also that whatsoever God doth, it continueth forever, and that nothing can be put unto it, nor taken from it: And that God doth it to the intent that men should fear him. 15 The thing that hath been, is now; and the thing that is for to come, hath been afore time: for God restoreth again the thing that was past.
