They are, of course, not a good thing and they endanger your salvation. But your still have time till you are judged, according to your works, just like Catholic I, Orthodox Kosta or Muslim Achmed ibn Khattab have time to complete their conversion.
No one is completely saved till he is living. We all undergo conversion all our lives.
