The Gospel is the joyous declaration that God is redeeming the world through
Christ (Matt 1:21; Luke 1:68; Eph 1:7; Col 1:20), and that He calls
everyone everywhere to repent from sin and trust Jesus Christ for salvation
(Mark 1:15; Acts 2:38; 17:30).
Each of us has sinned against God (Rom 3:23), breaking his law and rebelling against his rule, and the penalty for our sin is death and hell (Rom 6:23). But because He loves us, God sent his Son Jesus (John
3:16; Eph 2:4; 1 John 4:10) to live for his people’s sake the perfect,
obedient life God requires (Rom 8:4; 1 Cor 1:30; Heb 4:15) and to die
in their place for their sin (Isa 53:5; Mat 20:28; 26:28; Mark 10:45; 14:24;
Luke 22:20; John 11:50-51; Rom 3:24-25; 4:25; 1 Cor 15:3; 2 Cor 5:21; Eph 5:2;
Heb 10:14; 1 Pet 3:18). On the third day, He rose bodily from the grave
(Mat 28:6) and now reigns in heaven (Luke 22:69; 24:51; Heb
8:1), offering forgiveness (Eph 1:7), righteousness (Rom
5:19), resurrection (Rom 8:11), and eternal blessedness in God’s
presence (Rev 22:4) to everyone who repents of sin and trusts solely in
Him for salvation.
