Ye have not yet resisted unto blood, striving against sin" (verse 4). The persons here immediately addressed—the "ye"—were the Hebrews themselves. Because of their profession of Christianity, because of their loyalty to Christ, they had suffered severely in various ways. Plain reference to something of what they had already been called on to endure is made in 10:32-34, "But call to remembrance the former days, in which, after ye were illuminated, ye endured a great fight of afflictions; partly whilst ye were made a gazing-stock both by reproaches and afflictions; and partly whilst ye became companions of them that were so used. For ye had compassion of me in my bonds, and took joyfully the spoiling of your goods." Thus, the Hebrew saints had been sorely oppressed by their unbelieving brethren among the Jews; it is that which gave such point to the exhortation and warning in the previous verse.
"Ye have not yet resisted unto blood, striving against sin." Here is the second consideration which the apostle pressed upon his afflicted brethren: not only to ponder the far greater opposition which their Savior encountered, but also to bear in mind that their own sufferings were not so severe as they might have been, or as possibly they would yet be. It is an argument made by reasoning from the greater to the less, and from comparing their present state with that which might await them: what could be expected to sustain their hearts and deliver from apostasy when under the supreme test of death by violence, if they fainted beneath lesser afflictions? We, too, should honestly face the same alternative: if unkind words and sneers make us waver now, how would we acquit ourselves if called on to face a martyr’s death!
The present state of the oppressed Hebrews is here expressed negatively: "ye have not yet resisted unto blood." True, they had already met with various forms of suffering, but not yet had they been called upon to lay down their lives. As Hebrews 10:32-34 clearly intimates, they had well acquitted themselves during the first stages of their trials, but their warfare was not yet ended. They had need to bear in mind that word of Christ, "Men ought always to pray, and not to faint" (Luke 18:1); and that exhortation of the Holy Spirit, "let us not be weary in well doing: for in due season we shall reap, if we faint not" (Gal. 6:9).
"Ye have not yet resisted unto blood." The apostle here hinted to the Hebrews what might yet have to be endured by them, namely a bloody and violent death—by stoning, or the sword, or fire. That is the utmost which fiendish persecutors can afflict. Men may kill the body, but when they have done that, they can do no more. God has set bounds to their rage: none will hound or harm His people in the next world! Those who engage in the Christian profession, who serve under the banner of Christ, have no guarantee that they may not be called unto the utmost suffering of blood on account of their allegiance to him; for that is what His adversaries have always desired. Hence, Christ bids us to "sit down and count the cost" (Luke 14:28), of being His disciples. God has decreed that many, in different ages should be martyred for His own praise, the glory of Christ and the honor of the Gospel.
"Ye have not yet resisted unto blood, striving against sin." "Sin" is here personified, regarded as a combatant which has to be overcome. The various persecutions, hardships, afflictions, difficulties of the way, in consequence of our attachment to Christ, become so many occasions and means which sin seeks to employ in order to hinder and oppose us. The Christian is called to a contest with sin. The apostle continues his allusion to the Grecian Games, changing from the racer to the combatant. The great contest is in the believer’s heart between grace and sin, the flesh and the spirit (Gal. 5:17). Sin seeks to quench faith and kill obedience: therefore sin is to be "striven against" for our very souls are at stake. There is no place for sloth in this deadly contest; no furloughs are granted!
"Striving against sin." That which the Hebrews were striving against was apostasy, going to the full lengths of sin—abandoning their Christian profession. Persecution was the means which indwelling depravity sought to use, to employ in slaying faith and fidelity to Christ. That terrible wickedness was to be steadfastly resisted, by fighting against weariness in the conflict. O to say with the apostle, "I am ready not to be bound only, but also to die at Jerusalem for the name of the Lord Jesus" (Acts 21:13): but in order to reach that state of soul, there has to be a close walking with Him day by day, and a patient bearing of the minor trials. "If thou hast run with the footmen and they have wearied thee, then how canst thou contend with horses? and if in the land of peace, wherein thou trustedst, they wearied thee, then how wilt thou do in the swelling of Jordan?" (Jer. 12:5).
