The Second Commandment
You shall not misuse the name of the Lord your God.
What does this mean? We should fear and love God so that we do not curse, swear, use satanic arts, lie or deceive by His name, but call upon it in every trouble, pray, praise, and give thanks.
The Law in the Second Commandment is that we are not to profane the name of God. Anything that profanes God’s name is a violation of this Commandment. We may not swear falsely in God’s name or we may not call down punishment in God’s name. We are to use God’s name in times of thanksgiving and praise, in times of trouble and in times of prayer. I may cry out “My God” in times of pain and suffering. I may cry out “O God” in times of praise and prayer.
The Gospel in the Second Commandment is that God give us his name. God wants to be in relationship with His people, and provides a way for that relationship, by giving us a name to cry out to or to praise. The name of God is the tetragrammaton (Hebrew: יהוה, YHWH), usually translated as “I Am Who I Am”.
