Sing praises to the LORD, O you his saints, and give thanks to his holy name. For his anger is but for a moment, and his favor is for a lifetime. Weeping may tarry for the night, but joy comes with the morning. — Psalm 30:4-5 (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
