Was it you or I who stumbled first? It does not matter. The one of us who finds the strength to get up first, must help the other.
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.
Even now one rarely hears of people achieving great things unless they first stumble in some respect.
