I have already completely fallen away and have come back in great measure....it is, as I understand it now, a part of the sanctification process, as we must "all live by every word of God" and if Bible talks about it, then you will experience it. Bible talks about falling away and losing your first love, and also true repentance. If you come back in this lifetime, it is a good thing and for your learning. Not all do. My falling away lead me to think in new ways and I created a website at **HERESY LINK REMOVED** to describe some of the things I learned if any interested.....
