Hebrews 10:26

“For if we sin wilfully, etc..]] Which is not to be understood of a single act of sin, but rather of a course of sinning; nor of sins of infirmity through temptation, or even of grosser acts of sin, but of voluntary ones; and not of all voluntary ones, or in which the will is engaged and concerned, but of such which are done on set purpose, resolutely and obstinately; and not of immoral practices, but of corrupt principles, and acting according to them; it intends a total apostasy from the truth, against light and evidence, joined with obstinacy. After that we have received the knowledge of the truth; either of Jesus Christ, or of the Scriptures, or of the Gospel, or of some particular…”

“Compare on this and following verses, Heb 6:4, &c. There the warning was that if there be not diligence in progressing, a falling off will take place, and apostasy may ensue: here it is, that if there be lukewarmness in Christian communion, apostasy may ensue. if we sin--Greek present participle: if we be found sinning, that is, not isolated acts, but a state of sin [ALFORD]. A violation not only of the law, but of the whole economy of the New Testament (Heb 10:28-29). wilfully--presumptuously, Greek "willingly." After receiving "full knowledge (so the Greek, compare Ti1 2:4) of the truth," by having been "enlightened," and by having "tasted" a certain measure even of grace of "the Holy…”

“For if we sin willfully after that we have received the knowledge of the truth - If after we are converted and become true Christians we should apostatize, it would be impossible to be recovered again, for there would be no other sacrifice for sin; no way by which we could be saved. This passage, however, like Hebrews 6:4-6, has given rise to much difference of opinion. But that the above is the correct interpretation, seems evident to me from the following considerations: (1) It is the natural and obvious interpretation, such as would occur probably to ninety-nine readers in a hundred, if there were no theory to support, and no fear that it would conflict with some other doctrine. (2) It…”

“For when we - Any of us Christians. Sin wilfully - By total apostasy from God, termed "drawing back," Heb 10:38. After having received the experimental knowledge of the gospel truth, there remaineth no more sacrifice for sins - None but that which we obstinately reject. Hebrews 10:28”

“10:26-31 The author interjects a strong warning concerning the danger of rejecting God’s Son and his authoritative word. The warning challenges hearers to respond with a commitment to follow Christ. 10:26-27 deliberately: Open rebellion against God’s laws was described as “sinning with a high hand” (see study note on Num 15:30-31). Here the author has in mind specifically a rejection of Christ and his work. Christ’s sacrifice for sins has done away with the sacrificial system of the old covenant (Heb 9:11–10:18). If a person rejects the Son’s sacrifice, there is no other sacrifice—nowhere else to go—for forgiveness. A person who rejects Christ can only expect judgment as one of God’s enemies…”
