20:20 And Moses said unto the people, Fear not: for God is come to {o} prove you, and that his fear may be before your faces, that ye sin not.
(o) Whether you will obey his precepts as you promised in Ex 19:8.
20:20 Fear not - That is, Think not that this thunder and fire is, designed to consume you. No; it was intended, To prove them, to try how they could like dealing with God immediately, without a mediator, and so to convince them how admirably well God had chosen for them in putting Moses into that office. Ever since Adam fled upon hearing God's voice in the garden, sinful man could not bear either to speak to God, or hear from him immediately. To keep them to their duty, and prevent their sinning against God. We must not fear with amazement; but we must always have in our minds a reverence of God's majesty, a dread of his displeasure, and an obedient regard to his sovereign authority.
20:18-21 This law, which is so extensive that we cannot measure it, so spiritual that we cannot evade it, and so reasonable that we cannot find fault with it, will be the rule of the future judgment of God, as it is for the present conduct of man. If tried by this rule, we shall find our lives have been passed in transgressions. And with this holy law and an awful judgment before us, who can despise the gospel of Christ? And the knowledge of the law shows our need of repentance. In every believer's heart sin is dethroned and crucified, the law of God is written, and the image of God renewed. The Holy Spirit enables him to hate sin and flee from it, to love and keep this law in sincerity and truth; nor will he cease to repent.
