At its core, the gospel is Jesus as the substitute for sinners. We could summarize the whole by saying that in his life Jesus lives in perfect submission to the will of God and he fulfills his righteous standard (the law).

In his death on the cross he quenches God’s wrath against sin, satisfying the sovereign demand for justice. In his resurrection he is victorious over sin and death. All of this is done on behalf of sinners in need of redemption and offered to all who believe. This is therefore very ‘good news.’

Here John Mac Arthur explains the heart of the gospel. Makes me want to shout THANK YOU JESUS!!!!
