Hebrews 10:26–31

Verse 26. If we sin wilfully. He speaks of the sin of wilful apostacy from the known truth; after which, as we cannot be baptized again, we cannot expect to have that abundant remission of sins, which Christ purchased by his death, applied to our souls in that ample manner as it is in baptism; but we have rather all manner of reason to look for a dreadful judgment; the more, because apostates from the know truth seldom or never have the grace to return to it.

Verse 28–29. A man making void, and so forth He brings this comparison from the manner that transgressors were dealt with under the law of Moses, to shew how much greater punishments Christians deserve when they are ungrateful to Christ after much greater benefits, when they may be said to have trodden under foot the Son of God by despising him, who was the author of their salvation, by shedding his blood upon the cross. Witham.—What is here said of the crime of apostacy, may in some measure be applied to every deadly sin committed after baptism or the sacrament of penance; for a Christian by returning to sin, treads under foot the Son of God, despises the adorable blood by which he was sanctified, and offers a henious affront to the spirit of grace. Apostacy, though enormous, like all other sins can be forgiven by true repentance; but the apostle declares, there is no victim for the guilt of a person who perseveres and dies in apostacy.

Verse 31. Man is mortal, and therefore cannot extend his vengeance beyond death; God is immortal, and, as he lives eternally, can punish eternally; and he who during life despises a God who died for him, will at death experience the rigour of a God always living to punish him.
