What Does It Mean to be the People of God?

Greeting

1:1 Paul, a servant [1] of Christ Jesus, called to be an apostle, set apart for the gospel of God, 2 which he promised beforehand through his prophets in the holy Scriptures, 3 concerning his Son, who was descended from David [2] according to the flesh 4 and was declared to be the Son of God in power according to the Spirit of holiness by his resurrection from the dead, Jesus Christ our Lord, 5 through whom we have received grace and apostleship to bring about the obedience of faith for the sake of his name among all the nations, 6 including you who are called to belong to Jesus Christ,

7 To all those in Rome who are loved by God and called to be saints:

Grace to you and peace from God our Father and the Lord Jesus Christ. (ESV)
