How great is the usefulness of every precept that delivers us from this great error, and leads us back to the true faith: that God, the Creator of all things, rules the Universe; that He must be served, loved, and feared, and not those imaginary deities. According to this faith we approach the true God, and obtain His favour without having recourse to burdensome means; for nothing else is required but to love and fear Him; this is the aim in serving God, as will be shown. Comp. "And now, Israel, what doth the Lord thy God require of thee but to fear the Lord?" &c. (Deut. x. 12)
