1 Remember also your Creator in the days of your youth, before the evil days come and the years draw near of which you will say, “I have no pleasure in them”; 2 before the sun and the light and the moon and the stars are darkened and the clouds return after the rain, 3 in the day when the keepers of the house tremble, and the strong men are bent, and the grinders cease because they are few, and those who look through the windows are dimmed, 4 and the doors on the street are shut—when the sound of the grinding is low, and one rises up at the sound of a bird, and all the daughters of song are brought low— 5 they are afraid also of what is high, and terrors are in the way; the almond tree blossoms, the grasshopper drags itself along,and desire fails, because man is going to his eternal home, and the mourners go about the streets— 6 before the silver cord is snapped, or the golden bowl is broken, or the pitcher is shattered at the fountain, or the wheel broken at the cistern, 7 and the dust returns to the earth as it was, and the spirit returns to God who gave it. 8 Vanity of vanities, says the Preacher; all is vanity.
Ecclesiastes 12:1-8

God offers a full life in an empty world

7 And now, O Lord my God, you have made your servant king in place of David my father, although I am but a little child. I do not know how to go out or come in. 8 And your servant is in the midst of your people whom you have chosen, a great people, too many to be numbered or counted for multitude. 9 Give your servant therefore an understanding mind to govern your people, that I may discern between good and evil, for who is able to govern this your great people?”

1 Kings 3:7-9

For when Solomon was old, his wives turned his heart away after other gods; and his heart was not wholly devoted to the LORD his God, as the heart of David his father had been.

1 Kings 11:4

1 Therefore, since we are surrounded by so great a cloud of witnesses, let us also lay aside every weight, and sin which clings so closely, and let us run with endurance the race that is set before us, 2 looking to Jesus, the founder and perfecter of our faith, who for the joy that was set before him endured the cross, despising the shame, and is seated at the right hand of the throne of God.

Hebrews 12:1-2

… let us run with endurance the race that is set before us, fixing our eyes on Jesus

13 The end of the matter; all has been heard. Fear God and keep his commandments, for this is the whole duty of man.14 For God will bring every deed into judgment, with every secret thing, whether good or evil.
Ecclesiastes 12:13-14

... let us lay aside every encumbrance and the sin which so easily entangles us, and let us run with endurance the race that is set before us, **fixing our eyes on Jesus **
Hebrews 12:1-2

“He who wants to keep his garden tidy doesn’t reserve a plot for weeds”
