Ecclesiastes 12:1; Ecclesiastes 12:8; Ecclesiastes 12:13-14

1 Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh , when thou shalt say , I have no pleasure in them;
8 Vanity of vanities, saith the preacher; all is vanity.
13 Let us hear the conclusion of the whole matter: Fear God, and keep his commandments: for this is the whole duty of man. 14 For God shall bring every work into judgment, with every secret thing , whether it be good, or whether it be evil.
