One gives freely, yet grows all the richer;
another withholds what he should give, and only suffers want.
Whoever brings blessing will be enriched,
and one who waters will himself be watered.
The people curse him who holds back grain,
but a blessing is on the head of him who sells it. (Proverbs 11:24-26 ESV)
The economy of God is greater than any government. So are His promises and rewards. The secret is a generous and gracious heart, and God is the sovereign benefactor who gives this heart to those who seek Him.
