Every believer is a member of the Body of Christ, and when two or more of those believers come together in Jesus' name, a church has formed. The Authority of that church is the Word of God, Jesus Christ. Matthew 7:28-29, “And it came to pass, when Jesus had ended these sayings, the people were astonished at his doctrine: For HE TAUGHT THEM AS ONE HAVING AUTHORITY, and not as the scribes.” God is an authoritative God, Who raises up authoritative preachers, to preach from an authoritative Book.
Hebrews 4:12, “For the word of God is quick, and powerful, and sharper than any two edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.” Amen! When we teach or preach the Word of God, we can do so with authority knowing that we have the PROMISES of God to back up everything we say. There is no controversy if you believe the Bible.
There is only one God (Deuteronomy 6:4). He is the creator of heaven and earth, and of all living beings. He has revealed Himself to humanity as the Father (Creator), in the son (Savior), and as the Holy Ghost (indwelling Spirit).
God is a Spirit (John 4:24). He is the Eternal One, the Creator of all things, and the Father of all humanity by creation.
He is the First and the Last, and beside Him there is no God (Isaiah 44:6).
There was no God formed before Him; neither shall be there any after Him (Isaiah 43:10).
Jesus is the Son of God according to the flesh (Romans 1:3) and the very God Himself according to the Spirit (Matthew 1:23). Jesus is the Christ (Matthew 16:16); the creator of all things (Colossians 1:16-17); God with us (Matthew 1:23); God made flesh (John 1:1-14); God manifested in the flesh (I Timothy 3:16);He which was, which is, and which is to come, the Almighty (Revelation 1:8);the mighty God, everlasting Father, and Prince of peace (Isaiah 9:6).
Jesus Himself testified of His identity as God when He said, "He that hath seen me hath seen the Father" (John 14:7-11) and "I and my Father are one" (John 10:30).
It took shedding of blood for the remission of the sins of the world (Hebrews 9:22), but God the Father was a Spirit and had no blood to shed. Thus He prepared a body of flesh and blood (Hebrews 10:5)and came to earth as a man in order to save us, for in Isaiah 43:11 He said, "Beside me there is no Saviour." When He came in flesh the angels sang, "For unto you is born this day in the city of David a Savior, which is Christ the Lord" (Luke 2:11).
The Holy Ghost is not a third person in the Godhead, but rather the Spirit of God (the Creator), the Spirit of the resurrected Christ. The Holy Ghost comes to dwell in the hearts and lives of everyone who believes and obeys the gospel, as the comforter, Sustainer, and keeper (John 14:16-26; Romans 8:9-11).
Sin is the transgression of the law, or commandments of God (I John 3:4). The guilt of sin has fallen upon all humanity from Adam until now (Romans 3:23). The wages of sin is eternal death (Romans 6:23; Revelation 20:14) to all those who refuse to accept salvation as set forth in the Word of God.
Salvation consists of deliverance from all sin and unrighteousness through the blood of Jesus Christ. The New Testament experience of salvation consists of repentance from sin, water baptism in the name of the Lord Jesus Christ for the remission of sins, and the baptism of the Holy Ghost, after which the Christian is to live a godly life (Acts 2:36-41).
Water baptism is an essential part of New Testament salvation and not merely a symbolic ritual. It is part of entering into the kingdom of God (God's church, the bride of Christ), and therefore, it is not merely a part of local church membership. (See John 3:5; Galatians 3:27).
