227. By means of doctrine not only is the Word understood, it also shines in the understanding, since it then becomes like a candelabrum with its lamps lighted. Thus man sees in it more things than he saw before, and also understands things he did not understand before; and things obscure and discordant he either passes over without seeing, or he so sees and explains them as to bring them into accord with doctrine. That the Word is looked at from doctrine and is explained according to it, the practice of the Christian world testifies. All the Reformed look at the Word from their own doctrine and explain it accordingly; likewise, the Papists from their doctrine, and even the Jews from theirs; consequently from false doctrines they see falsities and from true doctrine truths. All this makes clear that true doctrine is like a lamp in the dark, or a guidepost by the wayside.
