What is the law of God stated in the Ten Commandments?

Answer: You shall have no other gods before me. You shall not make for yourself an idol. You shall not misuse the name of the LORD your God. Remember the Sabbath day by keeping it holy. Honor your father and your mother. You shall not murder. You shall not commit adultery. You shall not steal. You shall not give false testimony. You shall not covet.

Exodus 20:1–3 KJV 1900

1 And God spake all these words, saying, 2 I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage. 3 Thou shalt have no other gods before me.

Why should the 10 Commandments be important to us today?

(1) Because they show us how holy God is

(2) Because they tell us what God expects of his people
