26 For if we sin deliberately after receiving the knowledge of the truth, there no longer remains a sacrifice for sins, 27 but a fearful prospect of judgment, and a fury of fire which will consume the adversaries. 28 A man who has violated the law of Moses dies without mercy at the testimony of two or three witnesses. 29 How much worse punishment do you think will be deserved by the man who has spurned the Son of God, and profaned the blood of the covenant by which he was sanctified, and outraged the Spirit of grace? 30 For we know him who said, "Vengeance is mine, I will repay." And again, "The Lord will judge his people." 31 It is a fearful thing to fall into the hands of the living God. 32 But recall the former days when, after you were enlightened, you endured a hard struggle with sufferings, 33 sometimes being publicly exposed to abuse and affliction, and sometimes being partners with those so treated. 34 For you had compassion on the prisoners, and you joyfully accepted the plundering of your property, since you knew that you yourselves had a better possession and an abiding one. 35 Therefore do not throw away your confidence, which has a great reward. 36 For you have need of endurance, so that you may do the will of God and receive what is promised. 37 "For yet a little while, and the coming one shall come and shall not tarry; 38 but my righteous one shall live by faith, and if he shrinks back, my soul has no pleasure in him." 39 But we are not of those who shrink back and are destroyed, but of those who have faith and keep their souls.

Commentary on Hebrews 10:26-31

(Read Hebrews 10:26-31)

The exhortations against apostacy and to perseverance, are urged by many strong reasons. The sin here mentioned is a total and final falling away, when men, with a full and fixed will and resolution, despise and reject Christ, the only Saviour; despise and resist the Spirit, the only Sanctifier; and despise and renounce the gospel, the only way of salvation, and the words of eternal life. Of this destruction God gives some notorious sinners, while on earth, a fearful foreboding in their consciences, with despair of being able to endure or to escape it. But what punishment can be sorer than to die without mercy? We answer, to die by mercy, by the mercy and grace which they have despised. How dreadful is the case, when not only the justice of God, but his abused grace and mercy call for vengeance! All this does not in the least mean that any souls who sorrow for sin will be shut out from mercy, or that any will be refused the benefit of Christ's sacrifice, who are willing to accept these blessings. Him that cometh unto Christ, he will in no wise cast out.

Commentary on Hebrews 10:32-39

(Read Hebrews 10:32-39)

Many and various afflictions united against the early Christians, and they had a great conflict. The Christian spirit is not a selfish spirit; it puts us upon pitying others, visiting them, helping them, and pleading for them. All things here are but shadows. The happiness of the saints in heaven will last for ever; enemies can never take it away as earthly goods. This will make rich amends for all we may lose and suffer here. The greatest part of the saints' happiness, as yet, is in promise. It is a trial of the patience of Christians, to be content to live after their work is done, and to stay for their reward till God's time to give it is come. He will soon come to them at death, to end all their sufferings, and to give them a crown of life. The Christian's present conflict may be sharp, but will be soon over. God never is pleased with the formal profession and outward duties and services of such as do not persevere; but he beholds them with great displeasure. And those who have been kept faithful in great trails for the time past, have reason to hope for the same grace to help them still to live by faith, till they receive the end of their faith and patience, even the salvation of their souls. Living by faith, and dying in faith, our souls are safe for ever.
