Is It Impossible to Restore Fallen Believers?

QUESTION: Explain the impossibility of renewing fallen believers, as stated in (1) Heb. 6:4-6 and (2) 10:26, 27.

ANSWER: The Hebrew Christian who apostatized to find favor with his Jewish kindred must abandon not only the practice of Christianity, but the theory also. Before restoration to the synagogue he must declare Jesus an accursed impostor, a malefactor, "a hanged man." So long as he is doing this he is crucifying the Son of God afresh, in the present tense, denoting continuousness, it is impossible for God, who respects free agency, to save him. In (2) the sinning willfully is another present tense. So long as willful sin continues the apostate can find in Judaism no effectual sacrifice, but, if he should turn to Christ, he will find that his sacrifice has not lost its virtue. So long as any man is abiding in a state of willing sin he is shutting the door of repentance behind him. God does not shut that door, the sinner shuts it himself, and he alone can open it. He is the first cause, the cause uncaused of all his moral acts. He is the creator of his own character and destiny.
