18 When all the people witnessed the thunder and lightning, the sound of the trumpet, and the mountain smoking, they were afraid and trembled and stood at a distance, 19 and said to Moses, "You speak to us, and we will listen; but do not let God speak to us, or we will die." 20 Moses said to the people, "Do not be afraid; for God has come only to test you and to put the fear of him upon you so that you do not sin." 21 Then the people stood at a distance, while Moses drew near to the thick darkness where God was.

Commentary on Exodus 20:18-21
(Read Exodus 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.
