The Third of the Trinity is the Spirit.  As the Father is the source of the Divine Trinity, the  Spirit is the consummation of the Divine Trinity.  All that the Father has and is, is embodied in the Son; and all that the Son is, is realized as the Spirit.  For this reason, He is called the Spirit of reality (John 15:26; 16:13; 1John 5:6). 

The reality of what Christ is and even of what the Triune God is, is the Holy Spirit.  This Holy Spirit carried out the incarnation of Christ (Luke 1:35; Matthew 1:18, 20).  Because He bears to us the humanity, human living, and the death of Jesus, He is called the Spirit of Jesus (Acts 16:7); and because the divinity and resurrection of Christ are made real to us by Him, He is called the Spirit of Christ (Romans 8:9).

He is also called the Spirit of Jesus Christ, indicating that He is the source of the bountiful supply to the believers (Philippians 1:19).  The Spirit of Jesus Christ is compounded with His humanity and death and with His divinity and resurrection.  This Spirit is the Spirit of life and the indwelling Spirit (Romans 8:2, 11).  As the Lord Spirit, He transforms us by renewing us (2 Corinthians 3:18; Titus 3:5).  The all-inclusive Spirit is our holy anointing (2Corinthians 1:21; 1John 2:20, 27), as typified by the compound ointment in Exodus 30:23-31.  As such, He becomes a seal and a pledge to us (Ephesians 1:13-14).

Daily the Spirit comforts us as our Paraclete (John 14:16-17), supplies us in our Christian walk, and intercedes for us (Romans 8:4, 26).  Such a Spirit was breathed into us as our life essentially (John 20:22) and was poured out upon us as power economically (Acts 2:1-4, 17).  In this age of degradation, this wonderful Spirit is intensified sevenfold as the seven Spirits of God (Revelation 1:4; 4:5; 5:6).  Eventually, this intensified Spirit, as the consummation of the Triune God, becomes one with the redeemed, regenerated, renewed, transformed, and glorified church, which is His bride, for the manifestation and expression of the Triune God in eternity (Revelation 22:17).
