The Fourteenth Revelation, Chapter 42
Context: This is our Lord’s will, that our prayer and our trust be both alike large. For if we trust not as much as we pray, we do not full worship to our Lord in our prayer, and also we tarry and pain our self. The cause is, as I believe, that we know not truly that our Lord is Ground on whom our prayer springeth; and also that we know not that it is given us by the grace of His love. For if we knew this, it would make us to trust to have, of our Lord’s gift, all that we desire. For I am sure that no man asketh mercy and grace with true meaning, but if mercy and grace be first given to him.

Costly Grace, p 43.
Costly Grace
Context: Cheap grace means grace as a doctrine, a principle, a system. It means forgiveness of sins proclaimed as a general truth, the love of God taught as the Christian "conception" of God. An intellectual assent to that idea is held to be of itself sufficient to secure remission of sins. The church which holds the correct doctrine of grace has, it is supposed, ipso facto a part of that grace. In such a Church the world finds a cheap covering for its sins; no contrition is required, still less any real desire to be delivered from sin. Cheap grace therefore amounts to a denial of the living Word of God, in fact, a denial of the Incarnation of the Word of God.
Cheap grace means the justification of sin without the justification of the sinner. Grace alone does everything, they say, and so everything can remain as it was before.
