There is a "flip" side to the coin called grace which literally means sanctification through favor......because mankind does nothing worth salvation as all have fallen short of the mark (every man sins through freewill -- Romans 3:23-24)....there is no flesh that can be justified in the eyes of God through the works of the Law in and by itself (Gal.2:16) as James declared, Works void of Faith through grace is Dead. Faith and Works compliment, not contradict. (James 2:5) One without the other is worthless. There is no doctrine of "once saved, always saved". Paul lived in fear that he would one day fall from grace as he described salvation as gift/prize that comes after the race called life is over......he declared it was a daily struggle to bring his carnal flesh under submission . (1 Cor. 9:24,27. 2 Tim. 4:7)
The other side of the coin? "It is a fearful thing to fall into the hands of the Living God." -- Heb.10:31. In fact, the scriptures declare that the beginning of wisdom is the fear of the Lord. (Prov. 9:10)
