The most striking aspect of the epistolary salutations in the New Testament letters is the complete absence of greetings from the Holy Spirit. In nearly every greeting, the writers send grace, mercy, and peace from God the Father and the Lord Jesus Christ, yet there is no mention of a personal greeting from the Holy Spirit across twenty epistles from five apostles. This consistent omission suggests that the Holy Spirit does not send greetings because it is not a distinct entity separate from the Father and the Son. Instead, the Holy Spirit is understood as the divine essence of both the Father and the Son, residing in God's chosen ones. Jesus Himself clarifies this in John 14, teaching that the Holy Spirit is not another personality but the shared essence of the Father and the Son. Paul reinforces this in II Corinthians 3:17, stating plainly, "Now the Lord is the Spirit," identifying the Spirit with Christ. Additionally, in Romans 8:26 and 34, the Spirit's intercession for us is equated with Christ's intercession, showing Their unity. The "Christ in you" statements, found in passages like Romans 8:10 and Galatians 2:20, further indicate that the Spirit of the Son abides with us. Broadly, the Holy Spirit represents the personality, mind, and power of God to accomplish His will throughout creation. For believers, it is the means by which the Father and the Son live in us, interact with us, empower us, and enable our relationship with Them. As Jesus prays in John 17:20-23, the unity between the Father and the Son extends to us through the Spirit, making us one with Them. When Christ is in us, the Father is in us also, uniting us with Both in spirit and guiding us to grow in character to reflect Their oneness.

The concept of the Holy Spirit as presented challenges the notion of a triune Godhead with three co-equal beings. Instead, it is asserted that the Holy Spirit is not a separate third person but is intrinsically linked to the Father and the Son. Jesus Christ Himself is identified as the Holy Spirit, emphasizing that it is Christ in us, the hope of glory, rather than a distinct entity. This understanding stems from Jesus' own words, where He declares that He will come to us, not a third person, through the Spirit that emanates from His mind, acting as a powerful communication from God to man. Jesus describes the Holy Spirit as the Spirit of truth, which He embodies, stating that He is the way, the truth, and the life. This Spirit, previously manifested in His physical presence as the Comforter for 3½ years, would continue as an invisible, spiritual force after His departure. He assures His disciples that He will not leave them comfortless but will come to them, manifesting Himself through this Spirit, reinforcing that it is He who dwells with and in them. Furthermore, both the Father and the Son are described as Spirit and holy, thus both are Holy Spirit. This unity and oneness between Them signify that the indwelling Spirit in believers is Jesus Christ, not a separate being. There is no indication of a third person in the Godhead having a relationship akin to that between the Father and the Son, nor is there evidence of the Holy Spirit being worshipped as a distinct entity, unlike the Father and the Son. Jesus' teachings highlight that the Spirit is an invisible power communicated from Him to us, empowering believers to understand, remember, overcome, witness, and glorify God, just as He did. This Spirit, being Christ in us, is the driving force preparing us for God's Kingdom, negating the existence of a trinitarian Godhead with a separate third person.

The Holy Spirit, when a personality is indicated by the context, is the Father or the Son. It is not a third person in a trinity. The Father Himself, by His Spirit, lives in us and directly interfaces with our mind to reveal His ways, purpose, plan, mind, attitude, perspective, character, love, power, mercy, and forgiveness. It is the Father who enables us, not a third party in a Godhead. Jesus Himself clarified that the works and miracles He performed were done by the Father, not by a separate entity. The Father that lives in us does the works, following the pattern established in the Son. The Holy Spirit is the essence of their mind, the power that issues forth from the Father and the Son, emanating directly from them to influence us personally. Jesus said, the Father and I are one, because their minds are so much alike. This direct and personal relationship with God, through His Spirit, stirs and excites our mind to understand things we would never grasp otherwise.

Brethren, we find a profound reason for hope in the indwelling guidance of God's Holy Spirit. Jesus Himself made this relationship deeply personal, declaring in John 14, "I will come to you," and later, "We will come and make Our home with him who loves Me." Thus, it is truly Him who lives in us as that Holy Spirit. This is an incredible truth. In John 16:33, He reminds us that in this world we will face tribulation, trials, and stress, but the same One who dwells within us encourages us to be of good cheer, for He has overcome the world. Our hope rests in this assurance that, just as He triumphed before, He can do so again in and through us. Jesus also promised that He will never leave nor forsake us, always remaining with us as the source of our strength and hope.

The Holy Spirit is not a separate entity or third person but is the essence of God's mind, shared by the Father and the Son. The Father and the Son are one in mind, heart, purpose, perspective, attitude, and spirit, which is the Holy Spirit. They dwell in us not as physical presences but through the transfer of Their characteristics, converting us as we yield to Them. This Spirit, the essence of Their mind, takes up residence in us, reflecting Their nature through our thoughts, attitudes, and actions. The Father and the Son are in us through this Spirit, representing a close relationship rather than a physical location. Their presence in us is to the degree that we reflect Them in our lives, embodying Their character and mind. The Holy Spirit, as the essence of God's mind, is what empowers and guides us, enabling us to be created in Their image without the need for a separate entity to inhabit us.

In understanding the nature of the Holy Spirit, we see through Scripture that the Spirit dwelling within us is not a separate third-party being, but rather the Spirit of the Son, Jesus Christ. As revealed in Galatians 4:6 and John 14, it is the Son Himself who indwells us. Jesus, being God, is spirit and holy, embodying the roles of our High Priest, Savior, and the Head of the church. His Spirit is the Spirit of truth, as noted in John 17, serving as our Comforter, Guide, Advocate, and Intercessor, fully qualified to dwell in us for His purposes. Furthermore, the Spirit is not only of the Son but also of the Father, for it is the same Spirit shared by Both. This unity of Spirit reflects Their oneness, not as one person, but as Beings of perfect agreement in mind and purpose, as Jesus expressed in John 10:30. This shared Spirit regenerates us as sons of God, drawing us toward the same unity They possess, a goal Jesus prayed for in John 17, that we may be one as They are one. The relationship between the Father and the Son, though marked by Their distinct roles and hierarchical order, underscores Their equality in essence as part of the God kind. Both are eternal, uncreated Spirit Beings, sharing the same divine nature. Yet, in function and authority, the Father is greater, as Jesus Himself declared in John 14:28, and to Whom He submits, as seen in various Scriptures like I Corinthians 15 and Revelation 3. This hierarchical arrangement does not diminish the Son's divinity but highlights Their unified purpose through distinct responsibilities, with the Spirit They share being the means by which we are connected to Their divine family.

The Bible uses the terms Christ in us, Spirit in us, and the Father in us as though they are one and the same, paralleling them to convey a unified concept. Jesus declared that He and the Father are one, sharing heart, mind, purpose, perspective, attitude, and spirit in perfect harmony, desiring to share these with us so we may be in harmony with Them and others. This does not imply a literal physical presence inside us, but rather a spiritual relationship where Their characteristics are manifested in us, much like parents' traits appear in their children through gestures, mannerisms, and speech. The Spirit of God dwells in us through this spiritual connection, not requiring a physical inhabitation, but through time spent with Him in prayer and Bible study, allowing His Word to flow into our minds. We imitate His characteristics, attitudes, and perspectives on life, learning from His guidance to take on the image of the Father and the Son, the family of God, through the transformative power of His Spirit and Word.

The essence of God's mind is transferred into ours through the direct actions of God Himself, working in us to will and to do. The Holy Spirit, when referred to as a person, is the Father Himself or the Son, depending on the context. There is no third party in the Godhead; it is the Father and the Son who actively work within us. God is a family, and as the Father, He personally raises His children, not delegating this responsibility to another entity. This intimate involvement ensures that the gifts and powers we receive are directly from Him, enabling us to carry out His will and grow in His image. The nearness of God is vital for this transference of His Spirit, as closeness facilitates the communication of His mind to ours, fostering a relationship that transforms us from glory to glory.
