Philippians 1:19 note 4
194 The revelation in the Bible concerning God, Christ, and the Spirit is progressive. The Spirit is mentioned first as the Spirit of God, in relation to creation (Gen. 1:2). Then, He is mentioned as the Spirit of Jehovah, in the context of God's relationship with man (Judg. 3:10; 1 Sam. 10:6); as the Holy Spirit, in relation to the conception and birth of Christ (Luke 1:35; Matt. 1:20); as the Spirit of Jesus, in relation to the Lord's human living (Acts 16:7); as the Spirit of Christ, in relation to the Lord's resurrection (Rom. 8:9); and here as the Spirit of Jesus Christ.
The Spirit of Jesus Christ is "the Spirit" mentioned in John 7:39. This is not merely the Spirit of God before the Lord's incarnation but the Spirit of God, the Holy Spirit with divinity, after the Lord's resurrection, compounded with the Lord's incarnation (humanity), human living under the cross, crucifixion, and resurrection. The holy anointing ointment in Exo. 30:23-25, a compound of olive oil and four kinds of spices, is a full type of this compound Spirit of God, who is now the Spirit of Jesus Christ. Here it is not the Spirit of Jesus (Acts 16:7) or the Spirit of Christ (Rom. 8:9) but the Spirit of Jesus Christ. The Spirit of Jesus is related mainly to the Lord's humanity and human living; the Spirit of Christ is related mainly to the Lord's resurrection. To experience the Lord's humanity, as illustrated in 2:5-8, we need the Spirit of Jesus. To experience the power of the Lord's resurrection, as mentioned in 3:10, we need the Spirit of Christ. In his suffering the apostle experienced both the Lord's suffering in His humanity and the Lord's resurrection. Hence, the Spirit to him was the Spirit of Jesus Christ, the compound, all-inclusive, life-giving Spirit of the Triune God. Such a Spirit has, and even is, the bountiful supply for a person like the apostle, who was experiencing and enjoying Christ in His human living and resurrection. Eventually, this compound Spirit of Jesus Christ becomes the seven Spirits of God, who are the seven lamps of fire before God's throne to carry out His administration on earth for the accomplishing of His economy concerning the church, and who are the seven eyes of the Lamb for the transfusing of all that He is into the church (Rev. 1:4; 4:5; 5:6).
