Since those who fall away from the faith are counted as having never been saved (their faith counted as righteousness is forgotten (Ez 18:24), their names blotted out of the Book of Life), in a way, those who have the faith never fall away, but continue on with the believers (1 Jn 2:19), which is, in an odd way, a form of OSAS--which frees me to accept and be comforted by the verses that speak of having been predestined, etc.
