The other day, it occurred to me to think about it in another way. Even if we have the best of intentions, the mentality described above separates us from God. We may think we are saying some thing perfectly kind. "Thanks, God. You're awesome. Now you've done enough and I got it from here. You don't have to give me any more of your grace. I will make myself closer to you." Yet, this attitude assumes that grace is only a thing, a possession that God hands out. We couldn't be more wrong. Grace is so much a part of God's character that if if we try to sidestep the flow pouring out of him, we are not moving toward him, but away from him. When we do not want to need the grace he gives, we do not just refuse a neatly wrapped package with a to from tag. We refuse God himself.
Here's a question to end with: Since God is Love, if we say we are worshiping God, but cannot believe that he will love us no matter what, are we even worshiping the right God?
