18 All the people, experiencing the thunder and lightning, the trumpet blast and the smoking mountain, were afraid - they pulled back and stood at a distance. 19 They said to Moses, "You speak to us and we'll listen, but don't have God speak to us or we'll die." 20 Moses spoke to the people: "Don't be afraid. God has come to test you and instill a deep and reverent awe within you so that you won't sin." 21 The people kept their distance while Moses approached the thick cloud 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.
