See Heb. 10:26-29; John 6:37; Heb. 6:4-6, and I John 1:9. The passage in Heb. 10 refers to those who sin after receiving "full knowledge" of the truth (see I Tim. 2:4), and who after having been "enlightened" and tasting a certain measure of grace and the spirit of truth (see John 14:17-29), apostatize to Judaism or infidelity. Such is not a sin of ignorance or error, but the result of moral wickedness or a deliberate sin against the Spirit--a presumptuous sin against Christ's redemption for us and the spirit of grace in us. Having fully known the one sacrifice for sin, and having a certain experience of the efficacy of that sacrifice, they have now rejected it In Heb. 6:4,6, the same idea is emphasized. Such sinners crucify Christ anew, instead of crucifying the world (see Gal. 6:14). The passage in John 6:37 expresses the glorious certainty of eternal life to those who believe and stand firm--those who are given him of the Father and come to him with full surrender. Not the simply willing, but the actually faithful; not the waverers, but the true and abiding, are to realize the promise. In the backslider there has been no complete dedication, otherwise there would be no apostasy. I John 1:9 emphasizes the assurance of forgiveness and acceptance of the faithful ones. Concerning the possibilities of a return to Christ on the part of a backslider, we can only assert that what to man may and often does seem impossible, is possible with God, and that his grace is boundless. Peter backslid in a most grievous way, and yet was forgiven. By a miracle of divine grace, the backslider, although beyond human hope of recall, may in God's abundant mercy find refuge and forgiveness.
