Let me observe, in the next place, that when I talk of simplicity in preaching, I would not have my readers suppose I mean childish preaching. If we suppose the poor like that sort of sermon, we are greatly mistaken. If our hearers once imagine we consider them a parcel of ignorant folks for whom any kind of ” infant’s food” is good enough, our chance of doing good is lost altogether.People do not like even the appearance of condescending preaching. They feel we are not treating them as equals, but inferiors. Human nature always dislikes that. They will at once put up their backs, stop their ears, and take offense, and then we might as well preach to the winds.
