1:1-7 The doctrine of which the apostle Paul wrote, set forth the fulfilment of the promises by the prophets. It spoke of the Son of God, even Jesus the Saviour, the promised Messiah, who came from David as to his human nature, but was also declared to be the Son of God, by the Divine power which raised him from the dead. The Christian profession does not consist in a notional knowledge or a bare assent, much less in perverse disputings, but in obedience. And all those, and those only, are brought to obedience of the faith, who are effectually called of Jesus Christ. Here is, 1. The privilege of Christians; they are beloved of God, and are members of that body which is beloved. 2. The duty of Christians; to be holy, hereunto are they called, called to be saints. These the apostle saluted, by wishing them grace to sanctify their souls, and peace to comfort their hearts, as springing from the free mercy of God, the reconciled Father of all believers, and coming to them through the Lord Jesus Christ.
5. By whom—as the ordained channel.
we have received grace—the whole "grace that bringeth salvation" (Tit 2:11).
and apostleship—for the publication of that "grace," and the organization of as many as receive it into churches of visible discipleship. (We prefer thus taking them as two distinct things, and not, with some good interpreters, as one—"the grace of apostleship").
for obedience to the faith—rather, "for the obedience of faith"—that is, in order to men's yielding themselves to the belief of God's saving message, which is the highest of all obedience.
for his name—that He might be glorified.
