2 Corinthians 9

Paul wrote that we receive the same way we give. If we give little, we will get back little and if we give in abundance, we will receive abundantly. We are not to give grudgingly or out of some sense of duty, but rather cheerfully, with joy in our hearts. When we give to others with the right attitude, God will supply our needs.

This doesn't mean we give in order to get back, but it is wonderful to know that God will provide for us when we follow His command to give. We don't need to worry about lacking what we need if we listen to God and obey Him. Giving with a cheerful heart stems from knowing that God takes care of us and helping others is a way of showing gratitude by becoming the instrument He uses to take care of others.
