Number 3 God’s Name should be, NEVER spoken in jest,
This one is pretty simple. Do not use the Lord's Name in vain. Period. There is power in the Name above all names. He is God. Our Saviour. Jesus. When we use it in a way that defies the reverence of Who He is I believe we grieve the Holy Spirit.....something we are commanded not to do. It's about honoring the most precious Name we can call on.
