1 [This letter is from] Paul, a slave of Jesus Christ, [who was] called to be an apostle, [and] set apart for [preaching] the Gospel of God.
2 God had promised this good news a long time ago through His prophets [and had it written] in the holy Scriptures [i.e., the Old Testament].
3 It was about His Son, Jesus Christ our Lord, who was born as a physical descendant of King David.
4 He was appointed to be the Son of God with power through the Spirit of holiness [Note: This could refer to the Holy Spirit] when He was raised from the dead.
5 It was through Jesus, and for His name’s sake, that we [i.e., I] received God’s favor to become an apostle, in order to bring about obedience based on faith from among people of all nations.
