Never work just for money or for power.  They won’t save your soul or help you sleep at night.

From 2 Chronicles 31:20-21:  “Hezekiah did this throughout all Judah; he did what was good and right and faithful before the Lord his God.  And every work that he undertook in the service of the house of God, and in accordance with the law and the commandments, to seek his God, he did with all his heart; and he prospered.”
