God influences the world through his people.  He gives to us so He and give through us.  The Bible tells us that everything we have is a gift from God (1 Chronicles 29:14).  As you give faithfully and willingly, the world is changed for the glory of God; the gospel is preached; lives are touched; people are fed; bodies are healed; churches are built; and you are blessed by God so that you can give again.
