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

1 Remember your Creator in the days of your youth, before the days of trouble come and the years approach when you will say, "I find no pleasure in them"--
8 "Meaningless! Meaningless!" says the Teacher. "Everything is meaningless!"
13 Now all has been heard; here is the conclusion of the matter: Fear God and keep his commandments, for this is the whole [duty] of man. 14 For God will bring every deed into judgment, including every hidden thing, whether it is good or evil.
