If we are a faithfully, fully repentant disciple of Christ then we fully transform as a person in HIS SPIRIT and HIS TRUTH. This cannot be helped because it is our desire to live FOR HIM and NOT FOR OURSELVES.
Our old worldly self dies and a new being emerges. When we are PLAYING at our salvation, we try and fool the WORLD around us that we are changing, but this false transformation does not fool God. We put on airs, we act one way in front of some people, another in front of others....but it is all for nothing.
There is nothing scarier than a Christian who is playing at being the thing he or she purports to be. And, at the end of days, the LORD is going to spit our lukewarm butts out first.
