The gospel means "good news," originating from the Greek word "euangelion." In Christianity, it specifically refers to the good news about Jesus Christ—who He is, what He has done, and why this matters for humanity. The gospel announces that Jesus, the Messiah, has brought the reign of God to the world through His life, death, and resurrection. The core message of the gospel includes:

• Who Jesus is: The Christ, the Savior, Lord, and King.
• What Jesus has done: He died on the cross for the forgiveness of sins and rose from the dead.
• Why He did this: To forgive sins and offer salvation and new life to humanity.
• How this is verified: It fulfills Old Testament scriptures and is witnessed by many eyewitnesses.
• How people should respond: By repentance (turning to God) and faith in Jesus.

The gospel is both a historical narrative and a call to believe in Jesus as Lord and Savior, promising forgiveness, reconciliation to God, and eternal life. It is considered the most important and life-changing message in Christianity—good news that offers hope and salvation.
