"How are we to know the voice of the Good Shepherd from the voice of a stranger? Can any person answer this question? I can. It is very easy. To every philosopher upon the earth, I say, your eye can be deceived, so can mine; your ear can be deceived, so can mine; the touch of your hand can be deceived, so can mine; but the Spirit of God filling the creature with revelation and the light of eternity, cannot be mistaken-the revelation which comes from God is never mistaken (DBY, 431)."
