Ecclesiastes 3:11-14; Ecclesiastes 3:22
He hath made all things good in their time, and hath delivered the world to their consideration, so that man cannot find out the work which God hath made from the beginning to the end.
And I have known that there was no better thing than to rejoice, and to do well in this life.
For every man that eateth and drinketh, and seeth good of his labour, this is the gift of God.
I have learned that all the works which God hath made, continue for ever: we cannot add any thing, nor take away from those things which God hath made that he may be feared.
And I have found that nothing is better than for a man to rejoice in his work, and that this is his portion. For who shall bring him to know the things that shall be after him?
