Acts 27:23

For there stood by me this night the angel of God
One of the ministering, spirits that stand before God, and who was sent by him to the apostle; and appeared to him, either in a vision by a dream, or rather when he was awake, and stood by him, as he was praying for deliverance from the storm; for it is most likely that the apostle should be engaged at such a time as this:

whose I am, and whom I serve:
meaning not the angel, but God, whose the angel was; and his the apostle was, by electing, redeeming, and calling grace; God the Father had chosen him in his Son unto salvation; and Christ had redeemed him by his blood; and the Holy Spirit had called him by his grace; and he was not only the Lord's in common, as all other saints are, but he was his apostle and minister, and served him in the ministration of the Gospel of Christ, as well as from a principle of grace, obeyed the law of God, and was subject to the ordinances of Christ; in all which he served with great pleasure and cheerfulness, diligence, constancy, and faithfulness; from right principles, and with right views, being constrained by love, and influenced by the consideration of the relation he stood in to God. And all this was not peculiar to the apostle, but common to all the saints, excepting that of his being an apostle and minister of the Gospel: and the consideration of their relation to God has the same influence upon them it had upon him; they are not their own, nor are they the servants of men, nor do they belong to Satan, nor even to the ministering angels, but they are the Lord's; not merely by creation, as all men are, but in a way of special grace: they are Jehovah the Father's, to whom he bears a peculiar love and favour, and whom he has chosen in his Son for his peculiar people; and which is made manifest and known by drawing them with loving kindness to himself in the effectual calling; by his Gospel coming in power to them; by the blessings of the covenant of grace being bestowed on them; and by the spirit of adoption witnessing to them, that they are the children of God: they are Jehovah the Son's, they are his people made willing in the day of his power; they are his portion assigned him by his Father; they are his spouse and bride, whom he has betrothed to himself; they are his children, to whom he stands in the relation of the everlasting Father; and they are his sheep the Father has given him, and he has laid down his life for; all which appears by their having his Spirit, as a Spirit of regeneration and sanctification, without which none are openly and manifestatively his: and they are Jehovah the Spirit's; they are his regenerated and sanctified ones; they are his workmanship, having his good work of grace begun and carrying on in their souls; they are his temples in which he dwells; he has the possession of them, and will not leave them till he has brought them safe to glory: and under all this evidence, and especially through the testimony of the Spirit of God unto them, they call themselves the Lord's, as the apostle here does, and this engages them to serve him. The natural man has no desire, but an aversion to the service of God; converted men are willing to serve him, and delight to do it; they serve God in the best manner they can, in righteousness and true holiness, in an acceptable manner, with reverence and godly fear, and heartily and willingly; as appears by the pleasure they take in being called the servants of God, by disclaiming all other lords, by running all risks to serve the Lord, and by lamenting it, that they serve him no better.
