What does 'gospel' mean in the context of this sermon?

In this context, the 'gospel' is defined as the good news that Jesus Christ, our Kinsman Redeemer, came to save sinners. This is encapsulated in 1 Timothy 1:15, which states, 'Christ Jesus came into the world to save sinners.' The gospel message underscores the sovereign grace of God and His initiative in redeeming His people, much like Boaz's role in Ruth's story. Instead of calling individuals to perform works for salvation, the gospel invites them to rest in the completed work of Christ and His love. Preaching the gospel is about demonstrating that salvation is a gift, not a reward, thus highlighting God's grace that seeks and saves those who cannot save themselves.
