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.
7. beloved of God—(Compare De 33:12; Col 3:12).
Grace, &c.—(See on Joh 1:14).
and peace—the peace which Christ made through the blood of His cross (Col 1:20), and which reflects into the believing bosom "the peace of God which passeth all understanding" (Php 4:7).
from God our Father, and the Lord Jesus Christ—"Nothing speaks more decisively for the divinity of Christ than these juxtapositions of Christ with the eternal God, which run through the whole language of Scripture, and the derivation of purely divine influences from Him also. The name of no man can be placed by the side of the Almighty. He only, in whom the Word of the Father who is Himself God became flesh, may be named beside Him; for men are commanded to honor Him even as they honor the Father (Joh 5:23)" [Olshausen].
