The one true God exists eternally as three persons—the Father, the Son and the Holy Spirit (Mark 12:29-30, Matt. 28:19, II Cor. 13:14).The Father is the Supreme Being, Creator, and Sustainer, deserving of human worship and obedience (Exodus 3:14, Psalm 121:1-2, John 14:8-9, Romans 8:15). The Son, Jesus Christ, is preexistent God manifested in the flesh by virgin birth. He lived a sinless life, died for our sins, bodily arose from the dead, ascended into heaven, is presently preparing a place for us as our high priest and is coming again (John 1:1, 14:29; Matt. 1:18-23; Heb. 4:15; I Pet. 3:18; I Cor. 15:3-19). The Holy Spirit is the third Person of the Trinity. He convicts the world of sin, unrighteousness, and judgment (John 16:8). At salvation, the Holy Spirit causes spiritual rebirth, indwells, seals, bestows gifts, and baptizes the believer into the Body of Christ (Rom. 8:9; I Cor. 2:12, 3:16, 12:11, 13). He continues to sanctify, guide, teach and fill the believer who walks in obedience to the Word (Acts 5:3-4; John 3:5; Rom. 8:9; Eph. 4:30; I Cor. 6:11, 19; Rom. 8:14; John 14:16-17; Eph. 5:18-21).
