Phillip Yancey, What's So Amazing About Grace, Zondervan, 1977, p. 180
There is one "catch" to grace that I must now mention. In the words of C.S. Lewis, "St. Augustine says &ls;God gives where He finds empty hands.' A man whose hands are full of parcels can't receive a gift." Grace, in other words, must be received. Lewis explains that what I have termed "grace abuse" stems from a confusion of condoning and forgiving: "To condone an evil is simply to ignore it, to treat it as if it were good. But forgiveness needs to be accepted as well as offered if it is to be complete: and a man who admits no guilt can accept no forgiveness." God took a great risk by announcing forgiveness in advance, and the scandal of grace involves a transfer of that risk to us.
