There is one living and true God, the creator of the universe (Exod. 15:11; Isa. 45:11; Jer. 27:5). He is revealed in the unity of the Godhead as God the Father, God the Son, and God the Holy Spirit, who are equal in every divine perfection (Exod. 15:11; Matt. 28:19; 2 Cor. 13:14).
God the Father is the supreme ruler of the universe. He providentially directs the affairs of history according to the purposes of His grace (Gen. 1; Ps. 19:1; Ps. 104; Heb. 1:1-3).
God the Son is the Savior of the world. Born of the virgin Mary (Matt. 1:18; Luke 1:26-35), He declared His deity among men (John 1:14, 18: Matt. 9:6), died on the cross as the only sacrifice for sin (Phil. 2:6-11), arose bodily from the grave (Luke 24:6,7,24-26; 1 Cor. 15:3-6), and ascended back to the Father (Acts 1:9-11; Mark 16:19). He is at the right hand of the Father, interceding for believers (Rom. 8:34; Heb. 7:25) until He returns to rapture them from the world (Acts 1:11; I Thess. 4:16-18).
God the Holy Spirit is the manifest presence of deity. He convicts of sin (John 16:8-11), teaches spiritual truths according to the written Word (John 16:12-15), permanently indwells believers (Acts 5:32; John 14:16,17,20,23), and confers on every believer at conversion the ability to render effective spiritual service (I Peter 4:10,11).
