The gospel — the good news — is fundamentally this: God loved the world enough to send his Son, and that Son's death and resurrection opened a door that no human achievement could open. Salvation is received, not achieved. Ephesians 2:8–9 makes the mechanics explicit: by grace, through faith, as a gift. Not of works. No one earns this.
Charismatic theology emphasizes the full scope of salvation — not just forgiveness of sin but the indwelling of the Holy Spirit, the restoration of relationship with God, and the beginning of a new life that is nothing less than resurrection life started now. Salvation isn't just about what happens after death. It's about what begins at the moment of new birth.
The confession in Romans 10:9 — "with thy mouth... with thine heart" — engages the whole person. Salvation isn't just intellectual agreement or an emotional experience. It involves the mouth (public declaration) and the heart (genuine belief). The Holy Spirit then seals and confirms the new life with his own presence — the promised gift to everyone who believes.
