Just a heads up: If you think you’re avoiding taking the Lord’s name in vain by saying “OMG” I promise you He knows what the “G” stands for.
If you think you’ve devised a way to speak flippantly of God, while not “technically” doing so, I’ve got news for ya: You’re not different than the Pharisees who thought they could have their cake and eat it too. They loved doing the outer things while their inner man was rotten. Rightly did Jesus call them out on their hypocrisy:
Woe unto you, scribes and Pharisees, hypocrites! for ye make clean the outside of the cup and of the platter, but within they are full of extortion and excess
Before you shout your favorite acronym, consider what you’re really saying.
Clean speech reflects a clean heart.
