The central belief of classical Pentecostalism is that through the death, burial, and resurrection of Jesus Christ, sins can be forgiven and humanity reconciled with God. This is the Gospel or "good news". The fundamental requirement of Pentecostalism is that one be born again. The new birth is received by the grace of God through faith in Christ as Lord and Savior. In being born again, the believer is regenerated, justified, adopted into the family of God, and the Holy Spirit's work of sanctification is initiated.
