True freedom is the gift of the Spirit, the result of grace: but, precisely because it is freedom FOR as well as freedom FROM, it isn't simply a matter of being forced now to be good, against our wills and without our cooperation, but a matter of being released from slavery precisely into responsibility, into being able at last to choose, to exercise moral muscle, knowing both that one is doing it oneself and that the Spirit is at work within, that God himself is doing that which I too am doing.
