Ye have not yet resisted unto blood, striving against sin.
Ye have not yet resisted unto blood,.... They had resisted sin, and Satan, and the world, the men of it, and the lusts of it, and its frowns and flatteries, and also false teachers, even every adversary of Christ, and their souls; but they had not, as yet, resisted unto blood, or to the shedding of their blood, as some of the Old Testament saints had done; as some in the times of the Maccabees, and as James the apostle of Christ, and as Christ himself: wherefore the apostle suggests, that they ought to consider, that they had been indulged; and what they had been engaged in, were only some light skirmishes; and that they must expect to suffer as long as they were in the world, and had blood in them; and that their blood, when called for, should be spilled for the sake of Christ:
striving against sin; which is the principal antagonist the believer has, and is here particular pointed out: sin is here, by some, thought to be put for sinful men; or it may design the sin of those men, who solicited the saints to a defection from the truth; or the sin of apostasy itself; or that of unbelief; or rather indwelling sin, and the lusts of the flesh, which war against the soul. Now this is said, to sharpen and increase the saints resentment and indignation against it, as being their antagonist, with whom they strive and combat, and which is the cause of all the evils in the world, exposes to wrath to come, and separates from communion with God; and to encourage them to bear their sufferings patiently, since they are not without sin, as Christ was; and since their afflictions and sufferings are for the subduing of sin, and the increase of holiness.
