10:26 sin wilfully. There is probably an allusion here to such Old Testament passages as Numbers 15:30-31; Deuteronomy 17:2-7; etc. The presumptuous sins (Psalm 19:13), especially of deliberate apostasy into idolatry and paganism, were punishable by death. In similar fashion, the deliberate rejection of Christ and His sacrifice for one’s sins, after one fully understands its significance and may even have made profession of faith therein, is without remedy. This is the only means God has provided, and there is nothing more than can be said or done to save such a person. That person already knows and understands it all, and has rejected it. See also the note on Hebrews 6:4-6. Such a person, regardless of outward appearances, had never truly committed his faith and life to Christ in the first place (I John 2:19). This verse does not, in context, apply to other sins of a true Christian (note Hebrews 10:39). The remedy for these is repentance and confession, for the blood of Christ has already paid for them (I John 1:7-9).
