There is but one God (Deut 6:4; Is 41:4; 43:10-13; 44:6-8), eternally existing in three equally and fully divine Persons: the Father, the Son, and the Holy Spirit, who know, love, and glorify one another (Mat 28:19; 2 Cor 13:14; 1 Pet 1:2). This one true and living God is infinitely perfect both in His love and in His holiness. He is the Creator of all things, visible and invisible, and is therefore worthy to receive all glory and adoration. Immortal and eternal, He perfectly and exhaustively knows the end from the beginning, sustains and sovereignty rules over all things, and providentially brings about His eternal good purposes to redeem a people for Himself and restore His fallen creation, to the praise of His glorious grace (Is 44:6-8; 45:5-7; Eph 1:3-14).
God the Father, the first Person of the Trinity, orders and disposes all things according to His own purpose and grace (Ps 145:8-9; 1 Cor 8:6). He is the Creator of all things (Gen 1:1-31; Eph 3:9) and is sufficient in Himself, not standing in need of any creature that He has made. (Acts 17:24-25). As the only absolute and omnipotent Ruler in the universe, He is sovereign in creation, providence, and redemption (Ps 103:19; Rom 11:36). His fatherhood involves both His designation within the Trinity and His relationship with humanity. As Creator, He is Father to all men (Acts 17:28), but He is spiritual Father only to believers (Rom 8:14; 2 Cor 6:18; Eph 4:6). He has decreed for His own glory all things that come to pass (Eph 1:11). He continually upholds, directs, and governs all creatures and events (1 Chron 29:11). He saves from sin all who come to Him through Jesus Christ, adopting them into His family (John 1:12; Rom 8:15; Gal 4:5; Heb 12:5-9). As Father to His children, He hears and answers prayer according to His wisdom, love, and providence. He will carry out all things in their proper time and order that they would consummate in Jesus Christ to reveal the supremacy of His name and purposes especially including the power of His love (Rom 11:33-36; Eph 1:11).
Jesus Christ, the second Person of the Trinity, is the Father’s only begotten eternal Son, very God of very God, who possesses all the divine excellencies, and thus He is coequal, consubstantial, and coeternal with the Father and is himself the image of the invisible God (John 10:30; 14:9; Col 1:15; Heb 1:3). Jesus Christ is creator of all things and by whom all things continue in existence and in operation. (John 1:3; Col 1:16-17; Heb 1:2). The Son of God became incarnate approximately 2000 years ago, grew “in wisdom and in stature and in favor with God and man” (Luke 2:52) all the while living and dying wholly obedient to the will of his Father and therefore, without sin (Heb 4:15; 1 Pet 2:22). This incarnation consisted in God the Son adding humanity to His deity. As a result of the incarnation, the Son of God became and remains, one person who exists in two natures, full deity and full humanity. None of the attributes of deity or humanity were erased, given over, inoperative, or forfeited in this union.
The Son of God was conceived by the power of the Holy Spirit and born of the Virgin Mary (Luke 1:35). He suffered under Pontius Pilate and was crucified. As a result of His crucifixion and the predetermined plan of God, the God-Man died a substitutionary and propitiatory death in the most absolute sense, the just for the unjust (Rom 3:25; 2 Cor 5:15; Heb 2:17; 1 John 2:2).
He was then buried and on the third day, rose bodily from the dead and appeared to many of His disciples (1 Cor 15:1-8). He ascended into heaven, where He sits now at the right hand of God the Father (Acts 1:9).
As a result of his accomplished work, He became the head over all things as uniquely demonstrated in the church, which is His body (Col1:18). Further, He does not cease to intercede and advocate for His people while seated at the right hand of the Father on high (Eph 1:22-23; Rom 8:34; Heb 7:25).
The Holy Spirit, the third Person of the Trinity, is eternally one with the Father and Son. He is underived, possessing all the attributes of personality and deity, including intellect (1 Cor 2:10-13), emotions (Eph 4:30), will (1 Cor 12:11), eternality (Heb 9:14), omnipresence (Ps 139:7-10), omniscience (Is 40:13-14), omnipotence (Rom 15:13), and truthfulness (John 16:13). In all the divine attribute, He is coequal, consubstantial, and coeternal with the Father and the Son (Mat 28:19; Acts 5:3-4; 28:25-26; 1 Cor 12:4-6; 2 Cor 13:14; Jer 31:31-34 with Heb 10:15-17). The salvation that Jesus Christ accomplished is applied to His people by the Holy Spirit. Sent by the Father and the Son, the Holy Spirit glorifies the Lord Jesus Christ, and, as the Helper, is present with and in believers (John 14:26; 15:26). His work includes convicting the world of sin, righteousness, and judgment. He also regenerates spiritually dead sinners, awakening them to repentance and faith. It is in and through Him that Christians are baptized into union with the Lord Jesus Christ (John 3:5-8; 16:7-11; Ez 37:14). By the Spirit’s work believers are renewed, sanctified, and adopted into God’s family. Through the Holy Spirit Christians participate in the divine nature and receive His sovereignly distributed gifts (Rom 5:5; 8:13-17; 15:16; 1 Cor 12:4-11; Titus 3:5; 1 Peter 1:2). The Holy Spirit is himself the down payment of the promised inheritance, and in this age indwells, guides, instructs, equips, revives, and empowers believers for Christ-like living and service (Acts 2:38; 5:32; Rom 8:9-11; 15:13; 1 Cor 6:19; Eph 1:13-14).
