What can God do? What limits does God have? Our usual answer would be God can do all things, he has no limits. The question isn't really what God can or can't do, but what is God willing to do in your life. Paul's answer would be that God can do more than we can imagine. He told the Philippian church, "I can do all things through Christ who strengthens me." So the question then becomes how much am I willing for God to do in my life?
When back in his hometown of Nazareth Jesus didn't do many miracles. Was it that his power was somehow less at home? Were there no problems, sickness for him to cure? I'm sure the answer was no on both accounts. Jesus hadn't lost any of his power and there were needs all around. But the home folk wouldn't let him because they couldn't see Jesus as any more than just the carpenter's son. The limits were placed on Jesus by others.
The same is true today. Any limits we feel towards God aren't due to his limits, but the limits we place on him. God wants to reveal himself to us. He wants us to know and believe the mystery that is his Son and the gospel message. He desires that we share that message with others. And to that end he is willing to give us anything and everything we need to accomplish his will. The limits come when we don't really believe that. Yes God can do miracles, just not in my life. Sure God uses people and empowers them, but it's always the other guy.
Don't limit abundant power of God with our limited view.
