God is generous and so He calls us to be as well. The old saying is this, "What has your heart, has your checkbook." This is ever so true. We give out of obedience to the word of God. In Malachi, you find the only place where God instructs us to "TEST HIM". The area He instructs us to test Him is in giving. We give because we know when we obey God, He will take care of us.
