The gospel of Jesus Christ—What is it?

from the old testament

• The gospel is most clearly outlined in the New Testament.

from the new testament

• The word “gospel” means “good news.” In the New Testament, that good news is the message that God sent His Son to save sinners (John 3:16). Paul summarized it clearly: “Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day” (1 Corinthians 15:3–4). Because Jesus died and rose again, the gospel is “the power of God for salvation to everyone who believes” (Romans 1:16).
• The reason this good news is necessary is that all people are guilty before God. While some try to save themselves, God’s Law only reveals sin—it cannot rescue us from it (Romans 3:20). Since “all have sinned and fall short of the glory of God” (Romans 3:23), all deserve death because “the wages of sin is death” (Romans 6:23a). Therefore, without the good news, the only message is that everyone deserves and will receive judgment. John added that to deny our sin is self-deception (1 John 1:8, 10).
• The answer to that judgment is the gospel—the sacrificial death of Christ that reconciles sinners to God. Forgiveness requires death, and Jesus’ substitutionary death provided the salvation we could never achieve on our own (Hebrews 9:22).
• By His death, believers are set apart for God, being “sanctified through the offering of the body of Jesus Christ once for all” (Hebrews 10:10). On the cross, He bore sin’s penalty and satisfied God’s justice (Romans 3:24–26), and His resurrection vindicated His work and secured life for all who are united to Him (Romans 4:25).
• The proper response to the gospel is repentance and faith. Paul wrote, “If you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved” (Romans 10:9). Peter likewise called his hearers to repent to be forgiven (Acts 2:38). Salvation cannot come through human effort since everything we humans do is tainted with sin. However, it can come by grace through faith (Ephesians 2:8–9; Titus 3:5).
• Believers are immediately justified and find peace with God (Romans 5:1). That is, they no longer face condemnation (Romans 8:1) because everyone in Christ is a new creation (2 Corinthians 5:17). Jesus promised eternal life and resurrection to those who trust Him (John 6:40). The gospel thus assures believers of God’s acceptance now and of eternal life in the future.
• Because salvation is found in no one else (Acts 4:12), the gospel of Jesus Christ must be proclaimed. The risen Lord sent believers to make disciples of all nations (Matthew 28:18–20). This mission is carried out with confidence because the gospel is God’s power to save (Romans 1:16) and because Christ Himself is with His people to the end (Matthew 28:20).

implications for today

If you feel the weight of your sin and realize the futility of trying to fix yourself, the gospel is for you: God has done what you cannot. He sent His Son to live the perfect life you could not. He then willingly died and rose again for your salvation. Your hope cannot be found in resolutions to do better; it can only rest in a living Savior who already did the work for you and welcomes sinners. He invites you to repent of your self-reliance and call on Him in faith.

When you are saved, you become a member of God’s family. At that moment, God begins a new life in you, making you more like Jesus through the power of the Spirit working within you. And this is more than just about where you will spend eternity. The same Jesus who promises eternal life will also sustain you in this life, teaching you to forgive others and giving you the courage to face suffering with hope. If you believe this message, tell someone, be baptized, gather with a gospel-preaching church, and learn to follow Jesus alongside others. For those still exploring, keep listening to Scripture’s testimony about Christ, ask questions, and pray for understanding. The risen Lord delights to save all who come to Him in simple trust.
