We believe that God created the heavens and the Earth and everything in it. He created us for perfect fellowship with him and we can only find true peace and happiness when we live in fellowship with Him. (Genesis 1-2).
We believe God is holy and without sin nor can his holy nature even look upon sin (Habakkuk 1:13; Isaiah 6:3-5). God is also love and Godly love is not coercive but allows for the objects of His love the freedom to reject him. Thus, sin entered the world through disobedience and cut mankind off from that perfect fellowship with our creator resulting in physical death (Romans 5:12). Scripture and our reality speaks to the fact that the whole world is a prisoner to sin, which destroys all that God created to be good (Galatians 3:22; Romans 8:20-24)
God’s love for us is not diminished by our sin, rather our sinful state of separation from God pains him. Out of his abundant love for us he set in motion a plan to rescue us from our sinful state without compromising his holy nature. That plan is Jesus. Redemption involved Jesus taking our sin in exchange for his righteousness (2 Cor. 5:21). A profession of faith in Jesus and his resurrection leads us to salvation in which our broken fellowship is restored with God so that we can commune with him and stand before him with full confidence (Romans 10:9; Ephesians 3:12). For believers, Christ gave two ordinances in which we identify with him: baptism (Matthew 28:19-20) and the Lord’s Supper (I Corinthians 11:24-34).
A steadfast faith in Christ is only possible with the aid of the Holy Spirit, which is given to us upon salvation (Ephesians 1:13). We believe that the Holy Spirit sanctifies, empowers, teaches, guides, and comforts us as we seek to glorify God and increase in personal holiness (John 16;7-14; Galatians 5:22-23). The sin nature still remains but its resolve is weakened as a result of the ministry of the Holy Spirit. Ultimately, our full restoration to perfection will only happen upon physical death in which we will finally be free from the pull of sin and be reunited in a heavenly state with God.
