It is tempting to suggest that OMG is a transgression of the third commandment.
(Ex 20:7) “You shall not take the name of the LORD your God in vain, for the LORD will not hold him guiltless who takes His name in vain.In truth, OMG is worse! In casual conversation - in discussions of the most mundane matters - where the issues of interest are the most pedestrian - OMG begins almost every sentence.
"And I was like, OMG, why would I want to have seconds of broccoli? I mean, MG, it is so green! But, OMG, she was like, 'have some more?' And I was like, 'No,' but she scooped more onto my plate. OMG, how clueless is that?"
What this tells me is that the person isn't so much using God's name in vain - they are just using the word "god" as a filler. As bad as it is to use the name of the One True and Living God in a way that dishonors Him - it is WORSE to not believe in God at all.
"OMG" betrays a diminished awareness of God - a senseless, unseeing, unknowing, blind deadness toward God.
(Rom 11:33-36) Oh, the depth of the riches both of the wisdom and knowledge of God! How unsearchable are His judgments and His ways past finding out!
“For who has known the mind of the LORD?
Or who has become His counselor?”
“Or who has first given to Him
And it shall be repaid to him?”
For of Him and through Him and to Him are all things, to whom be glory forever. Amen.
(1Tim 1:17) Now to the King eternal, immortal, invisible, to God who alone is wise, be honor and glory forever and ever. Amen.
