Those who treat their God with contempt will be punished for their sin. But those who curse the Lord’s name must be put to death.
Leviticus 24:15–16
Many laws found in the Old Testament are no longer required. A lot of commandments are no longer commanded. A lot of the Old Testament law is ancient history this side of the cross, but some commandments will never, ever be removed. Some sins will always be sinful, and this is one: to curse the Lord’s name.
Though death is no longer the punishment for sin in the life of the believer, using the name of the Lord as a curse word is still sinful. When you use his name in anger, frustration, pain, or even excitement, it’s a sinful and ugly thing. In the time before Christ it was so ugly that unlike a lot of other sins mentioned, it had no sacrifice. The punishment was death. This shows you what an ugly and unacceptable sin it is in the eyes of God.
God’s name must be honored and respected, not used as a curse. As a God Girl you should make your faith obvious to all, and cursing his name proves your disobedience. Don’t let God’s name be used in vain. Get rid of all that kind of talk, and honor God by honoring his name. Give God the respect he deserves.
