The Holy Spirit is not a separate third divine Person but the divine essence, personality, mind, and power of both the Father and the Son, which comes to and resides in each of God's chosen sons and daughters. Jesus Himself explains this in John 14. Because Christ is the One who most often interacts with humans, the apostles frequently identify Him as the Spirit, as when Paul states, "Now the Lord is the Spirit" (II Corinthians 3:17). Paul likewise equates the Spirit's intercession for us (Romans 8:26) with Christ's intercession at the right hand of God (verse 34). The "Christ in you" statements (Romans 8:10; Galatians 2:20; Ephesians 3:17; Colossians 1:27) carry the same sense: the Spirit of the Son lives, abides, and continues with us. For those who believe and love God, the Spirit is the means by which the Father and the Son live in us, interact with us, empower us, and enable us as our relationship with them develops. In a way humans cannot fully fathom, the Spirit is both of them in us, uniting us with them, as Jesus prays in John 17:20-23. Since the Father and the Son are fully united, when Christ is in us the Father is in us also, so we are united with both in spirit and are growing to be united with them in character. This is also why the epistles' salutations never send greetings from the Holy Spirit.

The Holy Spirit in us represents the essence of God's mind, taking up residence in our hearts and minds to transform us into the image of the Father and the Son. It is not a physical presence but a spiritual union, reflecting a close relationship with God, where His characteristics, mind, character, attitudes, perspectives, morals, love, faithfulness, and submission to the Father are transferred to us as we yield to Him. Through His Spirit, God actively works to convert us, putting His laws into our hearts and writing them in our minds, a supernatural act of creation that shapes us like a potter forms clay. This Spirit empowers us to change from glory to glory, enabling us to believe and carry out His will through His Word and direct involvement in our lives. God sends forth His Spirit to project His thoughts into our minds, triggering choices and inspiring actions that align with His purpose, as He did when making us aware of imperatives like keeping the Sabbath. It is by His Spirit that we are created, prepared to understand and receive the essence of His mind, so that we may reflect His character and morals, becoming like Him in the image of our Father. The Holy Spirit, as the essence of God's mind, resides in us, not as a physical entity, but through the influence of His truth and power, guiding us to submit to His will and keep His law in spirit, not just in letter. God has empowered us to worship Him in spirit and truth, focusing His attention on us as the apple of His eye, developing His presence in us as we grow in union with Him and the Son. This transformative process is fueled by His Spirit, which purifies our thinking and impels us toward abundant and everlasting life, glorifying Him through our conduct and relationship with Him.

The Holy Spirit is the power and mind of God, not a third being and not a trinity. Scripture speaks of it being poured out, dwelling in us, and filling us, which cannot be said of a person. It is given only to those God calls, who repent, change their lives to live by every Word of God, and are baptized. It is a gift that cannot be earned. After baptism it opens our minds to God's laws, doctrines, and way of life, which no one can fully grasp without it, however smart or educated. It gives the power to change, the faith to overcome sin, and the ability to yield and be led by it. It also intercedes for us, helping us pray for what we do not know to ask. As God works in us, it shapes traits that produce the fruit of the Spirit: love, joy, peace, long suffering, kindness, goodness, faithfulness, gentleness, and self-control. Those who keep God's commandments know that God abides in them by the Spirit He has given. It makes us sons of God and imparts eternal life, since the same Spirit that raised Christ will give life to our mortal bodies. Understanding what the Spirit is guards against confusion like the trinity teaching and is part of the armor of God. Many have thrown away this gift by drifting back into confusion and the ways of the world.

The Holy Spirit is the essence of God's mind, embodying His power over all creation and residing in the sovereignty of His governance and purpose. It is through His Spirit that God acts instantaneously to ensure His will is done, with an awareness so vast and precise that no thought can be withheld from Him. God's Spirit interfaces with man's spirit, enabling revelation, illumination, and inspiration, which are essential for spiritual creation and transformation. These processes allow us to know that God is, to understand Him as our Creator, Savior, and Friend, and to align with His purpose for true success in life. God's Spirit is holy, distinct, and transcendentally pure, infinitely good in all it motivates and energizes, surpassing the spirits of man or satan in purity, knowledge, and character. It replaces the destructive mood and attitude of satan's spirit with one that is joyous, positive, and selfless, freeing us from bondage to failure. By His Spirit, God equips us to discern rightly and make good choices, providing the inclination and power to use knowledge for good rather than evil. The Holy Spirit, as the essence of God's mind, reveals knowledge of Himself and His works through words that are spirit and life, quickening and making alive. Unlike human words, which may not always bring life, God's words consistently activate and motivate when they reach our minds. Through His Spirit, God directly and personally interfaces with us, drawing us to Him in a calling that varies in form but always involves His revelation and transformative power.
