True genuine repentance carries a humbling of ones self, which is the denying of self, picking up your cross, that is of your own volition, putting the old man to death. It's one losing his life to save it. We are to mortify the flesh, by not yielding to the lust or making provisions for it to obey its carnal pulls. It takes submission to God, resisting the devil (self, the old man) for to be carnally minded is death. It takes an attitude of humility not thinking more highly of ones self, than you should.
