Costly grace is the gospel which must be sought again and again, the gift which must be asked for, the door at which a man must knock.

As brother stands by brother in distress, binding up his wounds and soothing his pain, so let us show our love towards our enemy. There is no deeper distress to be found in the world, no pain more bitter than our enemy's. Nowhere is service more necessary or more blessed than when we serve our enemies.

The church is not a religious community of worshippers of Christ but is Christ himself who has taken form among people.

The world upon whom grace is thrust as a bargain will grow tired of it.

Whenever Christ calls us, His call leads us to death.

To be sure, God shall call you, and us, only at the hour that God has chosen. Until that hour, which lies in God's hand alone, we shall be protected even in the greatest danger; and from our gratitude for such protection ever new readiness surely arises for the final call

Discipleship means adherence to Christ and, because Christ is the object of that adherence, it must take the form of discipleship. An abstract theology, a doctrinal system, a general religious knowledge of the subject of grace or the forgiveness of sins, render discipleship superfluous, and in fact exclude any idea of discipleship whatsoever, and are essentially inimical to the whole conception of following Christ....Christianity without the living Christ is inevitably Christianity without discipleship, and Christianity without discipleship is always Christianity without Christ.
