One term that will rarely fail to get me to stop listening is the term "cheap grace," as in this quote.
Grace, by its very definition, is a free gift from God. The implication of the use of this phrase is that most of us have earned our grace, but not this other person.
The other side is that no grace is cheap. It was purchased with our Savior's blood. And our acceptance of, but not our access to, that grace may demand of us nothing less.
