35 Therefore do not cast away your confidence, which has great reward. 36 For you have need of endurance, so that after you have done the will of God, you may receive the promise: 37 “For yet a little while, and He who is coming will come and will not tarry. 38 Now the just shall live by faith; But if anyone draws back, My soul has no pleasure in him.” 39 But we are not of those who draw back to perdition, but of those who believe to the saving of the soul. (Hebrews 10:35–39, NKJV)
This passage presents a substantial problem for those who believe the “once saved, always saved” doctrine. Christians are urged to have endurance to “receive the promise.” Without a faith that endures, they would cast away their confidence and “draw back to perdition” (destruction). This is a far cry from comforting souls in sin that they cannot lose their salvation. This passage also confounds those who trust in the “faith only” doctrine. It points out the promise of life is not received until after “you have done the will of God.” Faith that saves the soul endures by continuing to do the will of God. Faith endures the struggles of suffering that come with following Jesus (Heb. 10:32-34). Enduring faith gives life (v. 37), it pleases God (v. 38), and it saves the soul (v. 39). “Indeed we count them blessed who endure” (Jas. 5:11).
