When you give, God will multiply back to you what you've sown. Know that when you have seed in the ground, God is going to turn His favor in your direction.
When you are faithful to God, He is always faithful back.

Proverbs 3:9-10
Honor the LORD with your wealth, with the first fruits of all your crops; then your barns will be filled to overflowing, and your vats will brim over with new wine.
