You are a beloved child of God. But please remember this, too: You are human. You cannot expect to eat perfectly, look perfect, or be perfect. When you stumble, pick yourself up, even if you have to do it again and again.
God's relationship with man does not work in a way in which man stumbles and then God has to drop what he is doing in order to lift him up; rather, man stumbles so that God can lift him up. Hence it is utterly impossible to truly diminish his glory.
