The Gospel is sheer good tidings, not demand but promise, not duty but gift. But in order that as promise and gift it may be realized in us, it takes on the character of moral admonishment in accordance with our nature. It does not want to force us, but it wants nothing other than that we freely and willingly accept in faith what God wants to give us. The will of God realizes itself in no other way than through our reason and will. That is why it is rightly said that a person, by the grace He receives, himself believes and himself turns from sin to God.
