The resurrection of Christ is God the Father's act of approval for what Jesus had done in his life and ministry, and particularly in his death on a cross.
Paul, a bond-servant of Christ Jesus, called as 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 born of a descendant of David according to the flesh,
4 who was declared the Son of God with power by the resurrection from the dead, according to the Spirit of holiness, Jesus Christ our Lord, (Rom 1:1-4 NAS)
Paul in Romans gave the lineage of Jesus saying that Jesus was predicted the Old Testament, and he was a descendant of King David. His resurrection from the dead authenticated his position as the Son of God. This resurrection was in harmony with the work of the Holy Spirit and it was through the power of God the Father. This placed a stamp of approval on Jesus Christ. What must not be forgotten is that Jesus earned and deserved all that he received. He is eternally the Son of God, but his victory over death was won by his ministry and suffering on the Cross.
