1 Timothy 2:5

“For there is one God, etc.] This does not so much regard the unity of God, with respect to himself, or his divine essence, though that is a truth; but does not carry in it any apparent and forcible reason why all men should be prayed for, for which it is produced; but the unity of God with respect to men, as that there is but one God, who is the Creator of all men, and who, in a providential way, is the Saviour of all men; and in a way of special grace is the one God, the one covenant God of all sorts of men, of Jews and Gentiles; for he has taken of the latter into the covenant of his grace, as well as the former, and has loved them with a special and distinguishing love, has chosen them in…”

“For there is one God--God's unity in essence and purpose is a proof of His comprehending all His human children alike (created in His image) in His offer of grace (compare the same argument from His unity, Rom 3:30; Gal 3:20); therefore all are to be prayed for. Ti1 2:4 is proved from Ti1 2:5; Ti1 2:1, from Ti1 2:4. The one God is common to all (Isa 45:22; Act 17:26). The one Mediator is mediator between God and all men potentially (Rom 3:29; Eph 4:5-6; Heb 8:6; Heb 9:15; Heb 12:24). They who have not this one God by one Mediator, have none: literally, a "go-between." The Greek order is not "and one mediator," but "one mediator also between . . . While God will have all men to be saved by…”

“For there is one God - This is a reason for offering prayer for all people, and for the declaration 1 Timothy 2:4 that God desires that all people should be saved. The reason is founded in the fact that he is the common Father of all the race, and that he must have the same desire for the welfare of all his children, He has made them of one blood Acts 17:26, and he must have the same interest in the happiness of all; compare Ephesians 4:6 note; Romans 3:30 note. And one Mediator between God and men - see Galatians 3:19-20 notes; Hebrews 9:15 note. This also is given as a reason why prayer should be offered for all, and a proof that God desires their salvation. The argument is, that there is…”

“For - Ti1 2:4 is proved by Ti1 2:5; Ti1 2:1, by Ti1 2:4. There is one God - And they who have not him, through the one Mediator, have no God. One mediator also - We could not rejoice that there is a God, were there not a mediator also; one who stands between God and men, to reconcile man to God, and to transact the whole affair of our salvation. This excludes all other mediators, as saints and angels, whom the Papists set up and idolatrously worship as such: just as the heathens of old set up many mediators, to pacify their superior gods. The man - Therefore all men are to apply to this mediator, "who gave himself for all." 1 Timothy 2:6”

“2:5-6 Compact teachings, as in this passage, occur throughout the letters to Timothy and Titus (see also 1 Tim 3:16; 2 Tim 1:9-10; 2:8, 11-13; Titus 3:4-7). They might be adapted bits of creeds, hymns, or prayers that were known to the churches. The doctrines referenced probably relate to Paul’s trouble with the false teachers; it appears that their teaching undercut the universal appeal of the Good News and the effectiveness of the Gentile mission. The false teachers also had a deficient understanding of Jesus and his salvation. 2:5 There is one God and therefore one mission encompassing all people (Rom 3:29-30; Gal 3:26-29). Using the phrase one God suggests a fundamental declaration of…”

“one God: Deu 6:4; Isa 44:6; Mar 12:29-33; Joh 17:3; Rom 3:29, Rom 3:30, Rom 10:12; Co1 8:6; Gal 3:20; Eph 4:6 and: Job 9:33; Heb 7:25, Heb 8:6, Heb 9:15, Heb 12:24 the man: Mat 1:23; Luk 2:10, Luk 2:11; Joh 1:14; Co1 15:45-47; Phi 2:6-8; Heb 2:6-13; Rev 1:13 1 Timothy 2:6”
