There is only one true and living God, eternally existent in three persons - Father, Son and Holy Spirit - who are of equal dignity and power. The Triune God is the creator and sustainer of the universe. He is infinite in knowledge, wisdom, power, holiness, justice, goodness, truth and love.
A) THE FATHER is eternally God. His qualities are always in perfection. We are encouraged to have closeness to God the Father - the believers 'Heavenly Father'. Before conversion, sin made this relationship totally impossible but a 'forgiven sinner' is able to fulfil his Heavenly Fathers hopes for His children, as found in Ephesians 4:23 - 24. God, the Father, is worthy of our genuine worship and He seeks such worship from our hearts.
B) THE SON is eternally God. He was conceived by the Holy Spirit and born of the virgin Mary as the 'Son of Man', being truly human and truly God. Jesus lived a perfect, sinless life on earth. He died on the cross as a sin-atoning sacrifice. He was resurrected bodily from the dead. He ascended into Heaven. He is presently seated at the right hand of God the Father, as the one and only mediator between the Holy God and mankind, having taken on Himself humanity - yet without sin. All authority in heaven and on earth has been given to Him by God the Father. He shall return to earth as judge of both the dead and the living.
C) THE HOLY SPIRIT is eternally God. He is fully God, as are the other persons in the Godhead. He regenerates, baptizes, seals and indwells all true believers at the moment of their conversion. In His Sovereignty, He gives spiritual gifts to equip every believer for service in the Local Church. Some gifts - such as apostleship, prophecy, tongues and healing (referred to as 'sign gifts') were limited in history to the foundational phase of the New Testament church, acting as a sign that Jesus was, indeed, the Christ.
