But, whether we know the reason of these commandments or no, if we only know that they come from "the only wise God, our Saviour," we may be sure that in the keeping of them there is great reward; we may go blindfold wherever the Word of God may lead us, and rest in the firm conviction that, in so doing, we are pursuing the very path of safety and peace. Human wisdom at the best is but a blind guide; human policy is a meter that dazzles and leads astray; and they who follow it walk in darkness, and know not whither they are going; but he "that walketh uprightly," that walks by the rule of God's infallible Word, will ever find that "he walketh surely," and that whatever duty he has to perform, whatever danger he has to face, "great peace have all they that love God's law, and nothing shall offend them.".
