The Third Commandment

Do not take the Lord's name in vain.
This one is pretty straightforward- only say "God" when you are talking to Him or about Him. Sadly, though this seems to be the simplest commandment, it is probably the one that is broken most often. How many times a day do you hear someone say, "Oh my God," as an exclamation instead of a way to connect with God?
It's sad how many people misuse the name of our Lord, but even worse still is the fact that many do not even realize they are sinning! As Christians, as God's children, we must stop this. The maltreatment of God's name is a disease that we are obligated to keep from spreading. We owe it to God.
The simplest way to cure this would be to just ask someone who says, "Oh my God" to stop. Hopefully, that person won't say "Oh my God" anymore, but if they persist, the best thing to do is to tell the person what what they say bothers you.
"Would you please not say 'Oh my God'?"
-It bothers me when people say his name incorrectly."
-I don't think it's right to use God's name unless you're talking to Him."
-It can't be right to misuse God's name."
-I don't know if you mean to, but you're kind of insulting Him."
Another word that insults God is 'goddammit'. Again, though they may not realize it, when people say 'goddammit' they are actually asking for Him to dam (send to Hell) whatever they are talking about.
And who are we to tell God that someone should suffer eternal damnation? He alone is the judge of that.
God's name is and always will be sacred. He made us, gave us all of our gifts, all of our abilities, all our our friends and family members... He has given us everything good in our lives. All good things come from our Lord, because He is purely good. And He loves us.
And even though we have sinned, He loves us. He sent us His only son, Jesus, down to us. And Jesus showed us how deep love truly is... even when the Church sentenced Jesus to death He still loved us. As One Bread, One Body states, "He knows all the skeletons in our closets, yet He chooses to be with us and within us. He wants to be with us, even when we don't want to be with ourselves. Jesus loves us even when we don't love ourselves. He loves us." The least we could do is respect His name.
