The gospel is the good news that God loves the world enough to give His only Son to die for our sin (John 3:16). The gospel is good news because our salvation and eternal life and home in heaven are guaranteed through Christ (John 14:1–4). “He has given us new birth into a living hope through the resurrection of Jesus Christ from the dead, and into an inheritance that can never perish, spoil or fade. This inheritance is kept in heaven for you” (1 Peter 1:3–4).
The gospel is good news when we understand that we do not (and cannot) earn our salvation; the work of redemption and justification is complete, having been finished on the cross (John 19:30). Jesus is the propitiation for our sins (1 John 2:2).
The gospel is the good news that we, who were once enemies of God, have been reconciled by the blood of Christ and adopted into the family of God (Romans 5:10; John 1:12). “See what great love the Father has lavished on us, that we should be called children of God! And that is what we are!” (1 John 3:1). The gospel is the good news that “there is now no condemnation for those who are in Christ Jesus” (Romans 8:1).
To reject the gospel is to embrace the bad news. Condemnation before God is the result of a lack of faith in the Son of God, God’s only provision for salvation. “For God did not send his Son into the world to condemn the world, but to save the world through him. Whoever believes in him is not condemned, but whoever does not believe stands condemned already because they have not believed in the name of God’s one and only Son” (John 3:17–18). God has given a doomed world good news: the Gospel of Jesus Christ!
