“When the church preaches the gospel as the power of God, as spiritual dynamic that can operate in men and change them, it is THEN that she deals with the social problem; not when she is talking about the social problem, and giving statistics and making moral appeals. That is a waste of time, and we must reject it as atemptation from the devil! I do not hesitate to say so. The devil is perfectly satisfied as long as the church is just reading, Sunday by Sunday, little moral essays, trying to give a little moral uplift, and making an appeal to people to be decent. I am certain that at such times the devil rejoices, because he knows that his kingdom will not be affected.”
Martyn Lloyd-Jones, (Ephesians – Darkness And Light)
