10:19-25 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.
25. assembling of ourselves together—The Greek, "episunagoge," is only found here and 2Th 2:1 (the gathering together of the elect to Christ at His coming, Mt 24:31). The assembling or gathering of ourselves for Christian communion in private and public, is an earnest of our being gathered together to Him at His appearing. Union is strength; continual assemblings together beget and foster love, and give good opportunities for "provoking to good works," by "exhorting one another" (Heb 3:13). Ignatius says, "When ye frequently, and in numbers meet together, the powers of Satan are overthrown, and his mischief is neutralized by your likemindedness in the faith." To neglect such assemblings together might end in apostasy at last. He avoids the Greek term "sunagoge," as suggesting the Jewish synagogue meetings (compare Re 2:9).
as the manner of some is—"manner," that is, habit, custom. This gentle expression proves he is not here as yet speaking of apostasy.
the day approaching—This, the shortest designation of the day of the Lord's coming, occurs elsewhere only in 1Co 3:13; a confirmation of the Pauline authorship of this Epistle. The Church being in all ages kept uncertain how soon Christ is coming, the day is, and has been, in each age, practically always near; whence, believers have been called on always to be watching for it as nigh at hand. The Hebrews were now living close upon One of those great types and foretastes of it, the destruction of Jerusalem (Mt 24:1, 2), "the bloody and fiery dawn of the great day; that day is the day of days, the ending day of all days, the settling day of all days, the day of the promotion of time into eternity, the day which, for the Church, breaks through and breaks off the night of the present world" [Delitzsch in Alford].
