The Bible – It is the inspired Word of God. It is complete and true. (2 Timothy 3:16)

God – There is one and only one living and true God. He is the Creator of all, has existed and always will, and rules over all. God reveals Himself as God the Father, God the Son, and God the Holy Spirit. (Genesis 1:1; Psalm 90:2)

Jesus – He is God’s Son. He has existed always, but lived on earth as a man. After living a perfect, sinless life, Jesus offered Himself as a perfect sacrifice for every human being by dying on the cross. He arose from the grave after three days, having defeated death and ascended to Heaven and will return one day to reign as King. (1 Corinthians 15:3-4)

The Holy Spirit – He works to bring all people to understand their need for Jesus Christ. He lives in every believer the moment they accept Jesus Christ as Savior. He never leaves the believer, but to experience His Power in our lives we must be obedient to His direction. (Ephesians 1:13-14)

Salvation – Is through faith in Jesus Christ as Lord and Savior, and what He did for me by sacrificing His Perfect Life on my behalf, a sinner. I can never earn my salvation because it is not what I did, but what Jesus did. It is a gift, but I must accept it. (Romans 10:9; Ephesians 2:8-9)

The Church – The Bible tells us the Church is the body of Christ in the world today. Its main purpose is to reach people for Jesus Christ and to disciple believers in their daily lives. (1 Corinthians 12:12-13)

Communion – We believe that the Lord’s Supper as observed in our church, symbolizes the Lord’s death and is open to all who have received Christ as their Lord and Savior. (1 Corinthians 11:17-34)

Baptism – We believe that baptism is a symbol of the believer’s identification with Christ in His burial and resurrection therefore profession of faith in Jesus Christ as your Lord and Savior is a prerequisite to baptism. (Romans 6:4-5) We believe that the only Scriptural mode of baptism is by immersion in water and is a prerequisite to our church membership.
