When my soul was embittered, when I was pricked in heart, I was brutish and ignorant; I was like a beast toward you. Nevertheless, I am continually with you; you hold my right hand. You guide me with your counsel, and afterward you will receive me to glory. — Psalm 73:21-24 (ESV)
Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver.
2 Corinthians 9:7
