The Holy Spirit A B Simpson Chapter 10 – The Holy Spirit in the Epistle to the Romans I. First, we have the witnessing Spirit. In Romans 1: 3, 4, the Lord Jesus Christ is said to have been “of the seed of David according to the flesh, and declared to be the Son of God with power, according to the Spirit of holiness, by the resurrection from the dead.” The Spirit of holiness has been interpreted to mean the divine nature of Jesus Christ, but it is quite proper and, indeed, a more simple interpretation to apply it directly to the Holy Ghost as a divine Person, witnessing to the divinity of the Lord Jesus Christ, by raising Him from the dead according to the will of the Father.
