The sixty-six books of the Bible as originally written were inspired by God, hence free from error. They constitute the only infallible guide in faith and practice (2 Timothy 3:16).
God created Adam and Eve in His own image (Genesis 1:26). By disobedience, they fell from their sinless state through the temptation by Satan. This fall plunged humanity into a state of sin and spiritual death and brought upon the entire race the sentence of eternal death. From this condition we can be saved only by the grace of God, through faith, on the basis of the work of Christ, and by the work of the Holy Spirit.
That Jesus Christ is the only begotten Son of the Father, conceived of the Holy Spirit, and born of the Virgin Mary. To bring salvation, He lived a sinless life and died on The Cross as the sinner's substitute, shedding His blood for the remission of sins. On the third day He rose from the dead in the body, which had been laid in the tomb. He ascended to Heaven at right hand of the Father, where He performs the ministry of intercession (Hebrews 7:25). He shall come again, personally and visibly, to complete His saving work and to fulfil the eternal plan of God.
The Holy Spirit is the third Person of the Godhead. He produces to man the work of Christ. By justification and adoption we are given a right standing before God (John 1:12).
When we have turned to God in sincere faith in the Lord Jesus Christ, we are accountable to God for living a life separated from sin and characterised by the fruit of the Spirit. It is our responsibility to contribute by word and deed to the universal spreading of the Gospel. At the end of the age, the bodies of the dead shall be raised. The righteous shall enter into full possession of an eternal inheritance in the presence of God, and the wicked shall be condemned to an eternal death (1 Thessalonians 5:23).
