Tech savvy professionals often come across this acronym OMG which stands for Oh My God in SMS and chat rooms.

When Jesus the sinless one was made sin so that we can become the righteousness of God, and He was crucified, He could not address God, whose work He had come to fulfill, as Father, but instead He had to call on God the Father, as God. He expressed from the cross, Oh My God, Oh My God (OMG, OMG) why have you forsaken me?

Matthew 27:46 (KJV)
46 And about the ninth hour Jesus cried with a loud voice, saying, Eli, Eli, lama sabachthani? that is to say, My God, my God, why hast thou forsaken me?
