There is one true God, eternally existing in three persons- Father, Son and Holy Spirit- each of whom possess equally all the attributes of Deity and the Characteristics of personality. (Matt. 28:10; John 10:30; Acts 5:3,4,; 2 Cor. 13:14)
God the Father
God the Father is the functional head of the Trinity (Father, Son and Holy Spirit). He sent the Son to obtain satisfaction for divine justice and to proclaim reconciliation. The Spirit He sent to teach the truth. He is spoken of as the Father of all creation, of angels, of Israel, of believers, and of Christ. (John 14-17, 20:17; Job 1:6; Psalms 103:13)
Jesus is God, the Living Word, who became flesh through His miraculous conception by the Holy Spirit and His virgin birth. Hence, He is perfect Deity and true humanity united in one person forever. He lived a sinless life, and voluntarily atoned for the sins of men by dying on the cross as their substitution, thus satisfying divine justice and accomplishing salvation for all who trusted in Him alone. He rose from the dead in the same body, though glorified in which He lived and died. He ascended bodily into heaven, and sat down at the right hand of God the Father, and there He, the only mediator between God and man, continually makes intercession for His own. (Matt. 1:20; John 1:1-2, Luke 1:34-35; Heb. 4:15; 1 Cor. 15; Acts 1:9-11; 1John 2:1).
The Holy Spirit
The Holy Spirit, the third person of the Trinity, has come into the world to reveal and glorify Christ and to apply the saving work of Christ to men. He convicts and draws sinners to Christ, imparts new life to them, continually indwells them from the moment of spiritual birth, baptizes them in the body of Christ, and seals them until the day of Redemption. (John 16:8-11; Titus 3:5; 1 Cor. 6:19; Romans 8:9b; 1 Cor. 12:13; Gal. 5:22-23). Man: man was originally created in the image of God, both male and female He created them. Man sinned by disobeying God; thus, he was alienated from his Creator. The historic fall brought all mankind under divine condemnation. Man’s nature is corrupted, and he is thus totally unable to please God. Every man is in need of regeneration and renewal by the Holy Spirit. (Gen. 1:26-27; Eph. 2:1; Romans 1:8, 3:10-20, 23 5:12, 7:21-25).
