The First Commandment
You shall have no other gods.
What does this mean? We should fear, love, and trust in God above all things.
The Second Commandment
You shall 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 Third Commandment
Remember the Sabbath day by keeping it holy.
What does this mean? We should fear and love God so that we do not despise preaching and His Word, but hold it sacred and gladly hear and learn it.
