God influences the world through his people. He gives to us so He can give through us. The Bible tells us that everything we have is a gift from God (1 Chronicles 29:14). As you give both 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, in turn, are blessed by God so that you can give again.
