We believe in God, a Spirit (John 4:24), One in character (Righteous, Just, Love, Omnipresent, Omniscient, Immutable, Truth), Three in personality:
God, the Father: planner of the great salvation for mankind, concerns Himself in grace towards every detail of the affairs of mankind, saving from sin and death all who trust Him through the finished work of the Lord Jesus Christ on the cross, hearing and answering the prayers of His saints. (Eph. 4:6, John 3:16, II Cor. 5:21, Isa. 53:6, II Peter 3:9).
God, the Son: fulfiller of the plan of the Father, was born in human flesh, not of a human father, but the seed of the Holy Spirit in the Virgin Mary, living a sinless life of example, making atonement for the sins of the world by His death on the cross, bodily rising from the grave in resurrection victory over sin, death, hell and Satan: ascending into Heaven, bestowing gifts to men to carry on His work while He intercedes as advocate of His saints until the rapture at which time He will receive His own unto Himself as he promised. (Matt 28:6; Matt 1:18; John 14:2,3,6; Eph. 16:8; Heb. 4:14-15; I Peter 2:21; I Thess. 4:16-18; I John 2:12; Rom. 8:34; Eph. 1:7, John 1:1).
God, the Holy Spirit: was sent by the Son to reprove the world of sin, righteousness, and judgment; to regenerate, sanctify, fill, empower, comfort, and anoint to the glory of the Lord Jesus Christ. (John 16:8; I Peter 1:12; Acts 9:31; Eph. 5:18).
