Romans 1:1-4 Paul, a servant of Jesus Christ, called to be an apostle, separated unto the gospel of God, 2 (Which he had promised afore by his prophets in the holy scriptures,) 3 Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh; 4 And declared to be the Son of God with power, according to the spirit of holiness, by the resurrection from the dead:

Jesus is born the seed of David according to the flesh and He is the Son of God with power, according to the spirit of holiness. Paul tells us that Jesus is both fully man and fully God. He is the God-Man. As Man, He was a descendant of David. As God, Jesus is the exact representation of God (Hebrews 1:3). He is divinely God characterised by holiness.
