THE FULL ASSURANCE OF FAITH

19Therefore, brothers, since we have confidence to enter the Most Holy Place by the blood of Jesus, 20by a new and living way opened for us through the curtain, that is, his body, 21and since we have a great priest over the house of God, 22let us draw near to God with a sincere heart in full assurance of faith, having our hearts sprinkled to cleanse us from a guilty conscience and having our bodies washed with pure water. 23Let us hold unswervingly to the hope we profess, for he who promised is faithful. 24And let us consider how we may spur one another on toward love and good deeds. 25Let us not give up meeting together, as some are in the habit of doing, but let us encourage one another—and all the more as you see the Day approaching.

26If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left, 27but only a fearful expectation of judgment and of raging fire that will consume the enemies of God. 28Anyone who rejected the law of Moses died without mercy on the testimony of two or three witnesses. 29How much more severely do you think a man deserves to be punished who has trampled the Son of God under foot, who has treated as an unholy thing the blood of the covenant that sanctified him, and who has insulted the Spirit of grace? 30For we know him who said, “It is mine to avenge; I will repay,”[a] and again, “The Lord will judge his people.”[b] 31It is a dreadful thing to fall into the hands of the living God.

32Remember those earlier days after you had received the light, when you stood your ground in a great contest in the face of suffering. 33Sometimes you were publicly exposed to insult and persecution; at other times you stood side by side with those who were so treated. 34You sympathized with those in prison and joyfully accepted the confiscation of your property, because you knew that you yourselves had better and lasting possessions.

35So do not throw away your confidence; it will be richly rewarded. 36You need to persevere so that when you have done the will of God, you will receive what he has promised. 37For in just a very little while,
“He who is coming will come and will not delay.
38But my righteous one[c] will live by faith.
And if he shrinks back,
I will not be pleased with him.”[d] 39But we are not of those who shrink back and are destroyed, but of those who believe and are saved.

From Matthew Henry’s Concise Commentary on the Bible

Verses 19-25 The apostle having closed the first part of the epistle, the doctrine is applied to practical purposes. As believers had an open way to the presence of God, it became them to use this privilege. The way and means by which Christians enjoy such privileges, is by the blood of Jesus, by the merit of that blood which he offered up as an atoning sacrifice. The agreement of infinite holiness with pardoning mercy, was not clearly understood till the human nature of Christ, the Son of God, was wounded and bruised for our sins. Our way to heaven is by a crucified Saviour; his death is to us the way of life, and to those who believe this, he will be precious. They must draw near to God; it would be contempt of Christ, still to keep at a distance. Their bodies were to be washed with pure water, alluding to the cleansings directed under the law: thus the use of water in baptism, was to remind Christians that their conduct should be pure and holy. While they derived comfort and grace from their reconciled Father to their own souls, they would adorn the doctrine of God their Saviour in all things. Believers are to consider how they can be of service to each other, especially stirring up each other to the more vigorous and abundant exercise of love, and the practice of good works. The communion of saints is a great help and privilege, and a means of stedfastness and perseverance. We should observe the coming of times of trial, and be thereby quickened to greater diligence. There is a trying day coming on all men, the day of our death.

Verses 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.

Verses 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.
