Always Consistent, Never Predictable

“Do not say what everybody expected you would say. Keep your sentences out of ruts. If you have already said, ‘Salvation is all of grace’ not not always add, ‘and not by human merit,’ but vary it and say, ‘Salvation is all of grace; self-righteousness has not a corner to hide its head in.’ . . . . Occasional resorts to this system of surprise will keep an audience in a state of proper expectancy” (Charles Spurgeon, Lectures to My Students, p. 137).
