Q. Is that all that is necessary to be known concerning the Law of God?
A. Yes. These are the principle things necessary to be known for thy instruction, with these additional observations relating to the Divine Law:
1. The Moral Law is unchangeable, universally obliging all Nations, Jews and Christians, in all places, and at all times, to the end of the world. For though the Ceremonial Law, which served only to typify and set forth to the Jews, through purifications and offerings, the Mysteries of our Redemption, was annulled at the Death of Christ, (in Whom It was accomplished,) and though the same may be said of the Judicial Law given by Moses, for the government of the Jewish Commonwealth; yet the Moral Law is, and will remain always the same.
2. All these Commandments are to be obeyed by us with the profoundest respect and filial fear, considering that the Lawgiver is Almighty, Omnipotent, and sees our thoughts afar off, and is certainly to be our Judge; and It is a fearful thing to fall into the hands of the living God. [Heb. 10:31 ONT] And that we may fear God not as slaves, but as dear children, according to this holy Law, consider that the Lawgiver is the Eternal Justice, the Perfection of Goodness and Truth Itself, Who has created us, and also redeemed us with the Precious Blood of His Dear Son, and protects and leads us by His Wise Providence, causing all things to work together for our good.
3. This love to God can't be kindled in our hearts by our own strength, without the assistance of God's Holy Spirit; therefore we must be instant in prayer, that God would be graciously pleased to inflame our hearts with love towards Himself, and that we may have a regard to all His Commandments.
4. If our obedience to these Commands proceeds from the fear of men, or out of vainglory, in order to be the more esteemed in the world, or from any other principle that from true love, it can't be acceptable in the Eyes of God, for it is hypocrisy.
5. We transgress the Law of God, not only by our own sins, but also by partaking in the sins of others, by commanding, counseling, or in any way assisting others to commit any wicked actions. For example, if I hire a cutthroat to murder my neighbor, I am myself a murderer. If I conceal stolen goods, I myself am guilty of stealing, etc.
Thou shalt know therefore, that the Lord thy God, he is God, a faithful God, who keeps covenant and mercy for them that love him, and for those that keep his commandments to a thousand generations. [Deut. 7:9 Brenton's LXX]
