'A stategy in which the church becomes a silent presence in the world is therefore an ineffectual form of mission, which reveals to non-Christians our doctrinal confusion and spiritual impotence rather than commending our humility. Good works done in silence are often a necessary part of pre-evangelism, but in themselves can only win others to moralism or repel them in bafflement. The sheep can be led into social righteousness, but they will not follow unless they hear the voice and words of the Shepherd.'
Richard Lovelace, Dynamics of Spiritual Life, p.283.
