I eventually realized that this condition also applies to my own life, that God can't MAKE me do anything. If I don't want to, or believe I can't, that's it. Game over, I "win." I can "beat" God at this game every time. Of course technically, one could argue that this doesn't really count as an inability on God's part, but an unwillingness on mine. This may be true, but the outcome is the same. God will not do in our lives what we believe He cannot do.
When I was a child, I wanted to be an international spy roaming the great countries of the world singlehandedly solving crime and defeating international evil. For a while, I wanted to be a fireman, running into burning buildings, saving beautiful women and babies. I also wanted to be an astronaut, exploring space and other planets. I'm sure some of you had similar goals when you were young.
But as people grow, the goals we had in childhood change. Some become impractical (very little chance of single-handedly conquering "international evil"), others less desirable (fire is HOT and did you know that you can't breathe smoke?). And some goals well, you just didn't understand. I mean, exploring space? Hey, space is big, I mean REALLY BIG. You may thing it's a long way to the neighborhood McDonald's, but that's just PEANUTS to space. (1)
So, God is omnipotent, all powerful. Well, sort of. God can do anything He wants. Well, mostly. There is one thing that God's unlimited power cannot do. He cannot overcome the "I can'ts" that we hold on to in our lives and we will be right. If we truly believe we can't accomplish something, nothing God will, not "can't" but "will" do can change that. He works through imperfect vessels by choice and as odd as it may sound, He is bound by that choice to the limitations of the vessel: us.
So, is there no hope of miracles? Is God to be rendered powerless in the world by our limitations? Of course not. As vessels, we must come to know that our limitations are really "invitations." Just because we can't doesn't mean God won't, we need to trust that His omnipotence can conquer our "I can'ts". As we come to understand our limitations, we can begin to recognize the ones that would be possible with God's omnipotent power. When we see "impossible to accomplish" as merely "need God's help here" then we know what we can expect God to do. I love CS Lewis' statement "We are what we believe we are." Wow, there is so much power in those 7 simple words.
When God spoke to Moses from the burning bush, Moses said "I can't" talk, "I can't" throw down my rod, "I can't" make them listen to me. But eventually Aaron would speak, Moses laid down his rod before God and when he picked it up again, it was no longer the rod of Moses it had become the Rod of God. Using that rod, everyone heard God through Moses.
