Matthew Poole and continuators on 1 Timothy 2:5

5 For there is one God, and one mediator between God and men, the man Christ Jesus .

The Apostle proves the universal love of God to men by two reasons, the unity of God, and the unity of the Mediatour: though there are divers societies and vast numbers of men, yet there is but one God, the Creatour and Preserver of all. If there were many Gods in Nature, it were conceivable that the God of Christians, were not the God of other men, and consequently that his good Will were confin'd to his own portion, leaving the rest to their several Deities. But since there is but one true God of the world, who has revealed himself in the Gospel, it necessarily follows that he is the God of all men in the relation of Creatour and Preserver. And from hence he concludes, God will have all men to be saved. He argues in the same manner that salvation by faith in Christ belongs to the Gentiles as well as the Iews: Rom. 3.28, 29. The Apostle adds, for the clearest assurance of his good Will of God to save men, that there is one mediator between God and men, the man Christ Iesus. When the sin of man had provok'd Divine Justice, and the guilt could not be expiated without satisfaction, God appointed his Son incarnate to mediate between his offended Majesty and his Rebellious Subjects. And 'tis observable, the parallel between the Unity of God, and the Unity of the Mediatour; as there is one God of all Nations, so there is one Mediatour of all. The strength of the Apostles argument from the Unity of the Mediatour is this: if there were many Mediatours, according to the Numbers of Nations in the world, there might be a suspition whether they were so worthy and so prevalent as to obtain the Grace of God, every one for those in whose behalf they did mediate. But since there is but one, and that he is able to save to the uttermost all that come to God by him, 'tis evident that all men have the same Mediatour, and that every one may be assured that God is willing he should be saved, and for that blessed end, should by Faith and Repentance accept the Covenant of Grace. The Apostle for the stronger Confirmation, specifies the Mediatour, th[illegible: 1 letter] man Christ Iesus, to encourage the hopes of all men, from the Communion they have with him in nature, that they may partake of his Salvation, and that this great Mediatour having come from heaven and assumed the infirmity of our nature, Heb. 4.15. will be inclined compassionately to assist them, and raise them to his heavenly Kingdom.
