Sometimes, I fear, we forget who God is. We forget he is the vineyard owner. He doesn't manage it; he made it. He doesn't supervise it; he created it. God is God. We should serve because he is God. He has no reason to be gracious to us other than he loves us and is gracious. But we have no reason to expect, much less demand, for him to be gracious except that he promised to be gracious. If we were to receive what we deserved, we would be left out and ignored at best and humiliated and condemned by normal expectations. But God does not treat us as we deserve. He extends to us the grace to do something worthwhile with our lives. He provides the atonement for our sins. He voluntarily promises us life with him. So how can we whine or quarrel when he has given us much more than is fair?
