11 This letter is from Paul, a slave of Christ Jesus, chosen by God to be an apostle and sent out to preach his Good News. 2 God promised this Good News long ago through his prophets in the holy Scriptures. 3 The Good News is about his Son. In his earthly life he was born into King David's family line, 4 and he was shown to be the Son of God when he was raised from the dead by the power of the Holy Spirit. He is Jesus Christ our Lord.

(Read Romans 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.
