The Bible is God-breathed making it the literal Word of God. God has revealed himself through His Word, and it is profitable for teaching, correction, and reproof. The Bible is without error and is complete truth.
We serve only one God who is the Creator and Sustainer of all things. He is omnipotent, omnipresent, and omniscient. God exists in three distinct persons: the Father, the Son, and the Holy Spirit - the holy trinity.
Jesus Christ is the incarnation of God in human flesh. Jesus is 100% God and 100% man. He lived a perfect, sinless life that no other person could ever live. Jesus purposefully gave up his life so that we may have our sins forgiven.
We are all sinners in need of a Savior. We cannot be good enough or do enough to earn our way to heaven. Anyone who repents, that is to turn away, from their sin and place their faith in Jesus Christ can receive forgiveness of their sins and salvation in Jesus Christ.
The Holy Spirit inhabits the heart of all who have believed and put their faith in Jesus Christ. The Spirit is one who allows the believer to lead a godly life. The Spirit provides correction and understanding of the Scriptures.
Jesus spoke of a day when he would return to earth from heaven. He will usher in a new heaven and new earth where sin and evil will be eradicated. Those who have placed their faith in Christ will take part in this new heaven and earth.
Every person who has placed their faith in Jesus Christ are now a part of the Church of Jesus Christ. While there are many local bodies of believers, often called churches, there is only Church which incorporates every believer who was and is.
