12. There is One Body and One Spirit

God sanctified the Body of Christ with one spirit, the spirit of truth.

The spirit of God is the Spirit that sanctifies the body of Christ.

In Daniel 9, the angel said, “Seventy weeks are determined to anoint most holy.”1Daniel 9:24; the same expression “most holy” קדש קדשים without the definite article was used to describe the anointing of the priesthood of Aaron and his sons in 1 Chronicles 23:13. Aaron was set apart to sanctify him as most holy, he and his sons forever, see; Exodus 40:13–15. 

The most holy was not a building but the body of Christ, with Christ as the head. In Daniel 10, the body of Christ appeared like a son of man speaking with the voice of a multitude.

The earliest manuscripts of Acts 1:5 read, “You in2The Greek describes “in spirit” not “with spirit.” This begins when John says, “I baptize you in water.” spirit will be baptized holy.”3ἐν Πνεύματι βαπτισθήσεσθε Ἁγίῳ, cf Matthew 1:20, “that which is conceived of spirit is holy” ἐκ Πνεύματός ἐστιν Ἁγίου, called “holy one” ἅγιον in Luke 1:35

To the Corinthians, Paul said, “We were all baptized in one spirit into one body” (1 Corinthians 12:13).  And to the Ephesians, he wrote, “There is one body and one spirit” (Ephesians 4:4). This “one spirit” is the spirit of the sanctuary, the spirit of truth. It sanctifies the body of Christ

In John 14, Jesus said, “If anyone loves Me, he will keep My Word … and My Father and I will come and make our home with him” (John 14:23). In John 17, Jesus asked the Father to “sanctify them in the truth” (John 17:7). In reply, God sanctified them with His holy spirit.

But as time went on, many departed from the truth of the gospel.

Paul said to the Corinthians, “If you receive a different spirit, which you have not received, or a different gospel … you may well put up with it” (1 Corinthians 11:4).

Receiving the spirit of truth is dependent on obedience to the teachings of Jesus Christ.

In Revelation, John described seven Spirits as seven messengers sent to seven Churches. To the Laodiceans, Jesus said, “I stand at the door and knock, if anyone hears My voice and opens the door, I will come into him” (Revelation 3:20). But to the Church at Philadelphia, He said, “I have put before you an open door that cannot be shut … You have kept My word” (Revelation 3:8).
