He is a spirit who has un-originated, immutable, eternal, and self-sustained existence. There is one sovereign, omniscient, omnipotent, universal, just, and merciful God who created all things and who is actively concerned with the destiny of all people.
He is God incarnate. He is the Word. He is the promised Messiah of the Old Testament. He took the form of man and lived a life of perfection and died as a substitutionary sacrifice to satisfy justice and become an atonement and payment for all the sins of humanity. He is raised from the dead and now sits on throne at the right hand of the Father.
His is a distinct personality in the Godhead. He was an active part of creation and was an active, divine influence in the birth, life, baptism, death, resurrection, and miracles of Jesus. He operates in the world, the church, and in the individual believer. He was instrumental in the inspiration of the scriptures which guide us today. As Christians we also are given the gift of the indwelling presence of the Holy Spirit.
People need to be redeemed (delivered) from the guilt and eternal consequences of their sins. This redemption is the forgiveness and justification that is brought about through the atonement by Jesus Christ in His death and resurrection. This free gift of God's grace is given to those who trust in Jesus Christ and manifest an obedient faith. Obedient believers are immersed into Jesus Christ. The redemptive process of salvation is called the new birth.
All scriptures in the Old and New Testament canon were written by men as moved by the Holy Spirit. Therefore, the scriptures have divine authority for all things pertaining to our faith and godly living. Having divine authorship says that they are the living voice of God. They are infallible and inerrant as written by the inspired men God chose. By these scriptures all people will be judged for eternity.
This is the gathering of believers called out of the world by Jesus into a body or family. The head of the church is Christ. Each church is governed locally and overseen by elders. It's the Kingdom of God on earth, promised to be built by Jesus. Its purpose is to teach, train, edify, exhort, convict, and admonish its members, and share the Gospel with the world. It's divine structural and operational instructions are given in the New Testament.
Man is the highest of God's creation on earth. All people have sinned and stand in need of redemption. All will die because of Adam's sin but remain eternally accountable for their sins alone. Forgiveness of those sins is available through Jesus' sacrifice. Our fleshly nature can be radically improved by the influence of the Holy Spirit through the Scriptures and His personally indwelling the individual.
