5 And have you completely forgotten this word of encouragement that addresses you as a father addresses his son? It says, "My son, do not make light of the Lord's discipline, and do not lose heart when he rebukes you, 6 because the Lord disciplines the one he loves, and he chastens everyone he accepts as his son."[1] 7 Endure hardship as discipline; God is treating you as his children. For what children are not disciplined by their father? 8 If you are not disciplined-and everyone undergoes discipline-then you are not legitimate, not true sons and daughters at all.
5 And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him: 6 For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth. 7 If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? 8 But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons.
5 And have you forgotten the exhortation that addresses you as sons? "My son, do not regard lightly the discipline of the Lord, nor be weary when reproved by him. 6 For the Lord disciplines the one he loves, and chastises every son whom he receives." 7 It is for discipline that you have to endure. God is treating you as sons. For what son is there whom his father does not discipline? 8 If you are left without discipline, in which all have participated, then you are illegitimate children and not sons.
5 So don't feel sorry for yourselves. Or have you forgotten how good parents treat children, and that God regards you as his children? My dear child, don't shrug off God's discipline, but don't be crushed by it either. 6 It's the child he loves that he disciplines; the child he embraces, he also corrects. 7 God is educating you; that's why you must never drop out. He's treating you as dear children. This trouble you're in isn't punishment; it's training, 8 the normal experience of children. Only irresponsible parents leave children to fend for themselves. Would you prefer an irresponsible God?
5 And you have forgotten the exhortation which speaks to you as to sons: "My son, do not despise the chastening of the Lord, Nor be discouraged when you are rebuked by Him; 6 For whom the Lord loves He chastens, And scourges every son whom He receives." 7 If you endure chastening, God deals with you as with sons; for what son is there whom a father does not chasten? 8 But if you are without chastening, of which all have become partakers, then you are illegitimate and not sons.
5 And have you forgotten the encouraging words God spoke to you as his children? He said, "My child, don't make light of the Lord 's discipline, and don't give up when he corrects you. 6 For the Lord disciplines those he loves, and he punishes each one he accepts as his child." 7 As you endure this divine discipline, remember that God is treating you as his own children. Who ever heard of a child who is never disciplined by its father? 8 If God doesn't discipline you as he does all of his children, it means that you are illegitimate and are not really his children at all.
Matthew Henry's Commentary on Hebrews 12:5-8
Commentary on Hebrews 12:1-11
(Read Hebrews 12:1-11)
The persevering obedience of faith in Christ, was the race set before the Hebrews, wherein they must either win the crown of glory, or have everlasting misery for their portion; and it is set before us. By the sin that does so easily beset us, understand that sin to which we are most prone, or to which we are most exposed, from habit, age, or circumstances. This is a most important exhortation; for while a man's darling sin, be it what it will, remains unsubdued, it will hinder him from running the Christian race, as it takes from him every motive for running, and gives power to every discouragement. When weary and faint in their minds, let them recollect that the holy Jesus suffered, to save them from eternal misery. By stedfastly looking to Jesus, their thoughts would strengthen holy affections, and keep under their carnal desires. Let us then frequently consider him. What are our little trials to his agonies, or even to our deserts? What are they to the sufferings of many others? There is a proneness in believers to grow weary, and to faint under trials and afflictions; this is from the imperfection of grace and the remains of corruption. Christians should not faint under their trials. Though their enemies and persecutors may be instruments to inflict sufferings, yet they are Divine chastisements; their heavenly Father has his hand in all, and his wise end to answer by all. They must not make light of afflictions, and be without feeling under them, for they are the hand and rod of God, and are his rebukes for sin. They must not despond and sink under trials, nor fret and repine, but bear up with faith and patience. God may let others alone in their sins, but he will correct sin in his own children. In this he acts as becomes a father. Our earthly parents sometimes may chasten us, to gratify their passion, rather than to reform our manners. But the Father of our souls never willingly grieves nor afflicts his children. It is always for our profit. Our whole life here is a state of childhood, and imperfect as to spiritual things; therefore we must submit to the discipline of such a state. When we come to a perfect state, we shall be fully reconciled to all God's chastisement of us now. God's correction is not condemnation; the chastening may be borne with patience, and greatly promote holiness. Let us then learn to consider the afflictions brought on us by the malice of men, as corrections sent by our wise and gracious Father, for our spiritual good.
