We read in Romans xii. an exhortation to the saints to yield themselves a living _sacrifice_, which sacrifice is their reasonable _service_. They were to do so in the way of not being conformed to the world, but transformed by the renewing of their minds. So here: the course of conduct which the Apostle had been exhorting the Philippians to pursue was an act of worship or service, and in particular it was a sacrifice, the sacrifice of their faith, the sacrifice in which their faith was expressed. Each believer in offering this sacrifice acts as a priest, being a member of the holy priesthood which offers to God spiritual sacrifices (1 Peter ii. 5). Such a man is not, indeed, a priest to make atonement, but he is a priest to present offerings through Christ his Head. The Philippians, then, in so far as they were, or were to be, yielding themselves in this manner to God, were priests who offered to God a spiritual sacrifice. Here let us notice, as we pass, that no religion is worth the name that has not its sacrifice through which the worshipper expresses his devotion. And in Christian religion the sacrifice is the consecration of the man and of his life to God's service in Christ. Let us all see to it what sacrifices we offer. This doctrine, then, of the priesthood and the sacrifice was verified in the case of the Philippians; and, by the same rule, it held true also in the case of Paul himself. He, as little as they, was priest to make atonement. But certainly when we see Paul so cordially yielding himself to the service of God in the gospel, and discharging his work with such willing labour and pains, we see in him one of Christ's priests offering himself to God a living sacrifice. Now is this all? or is something more to be said of Paul? More is to be said; and although the point now in view is not prominent in this passage, it is present as the underlying thought. For the whole sacrifice of holy life rendered by the Philippians, and by his other converts, was, in a sense, the offering of Paul also; not theirs only, but his too. God gave him a standing in the matter, which he, at least, was not to overlook. God's grace, indeed, had wrought the work, and Paul was but an instrument; yet so an instrument, that he had a living and abiding interest in the result. He was not an instrument mechanically interposed, but one whose faith and love had wrought to bring the result to pass. To him it had been given to labour and pray, to watch and guide, to spend and to be spent. And when the Apostle saw the lives of many true followers of Christ unfold as the result of his ministry, he could think that God owned his place too in bringing all this tribute to the temple. "God grants me a standing in the service of this offering. The Philippians bring it, each for himself, and it is theirs; but I also bring it, and it is my offering too. God takes it at their hand, but also at my hand, as something which with all my heart I have laboured for and won, and
