How do we know that the Gospel is for sinners?

The assurance that the Gospel is for sinners comes directly from Jesus' statement in Luke 5:31-32, where He emphasizes that He did not come to call the righteous but sinners to repentance. This illustrates God's grace and mercy extended to those who are often marginalized by society, emphasizing that the sick and sinful are the very individuals whom Christ seeks to heal. The entire redemptive narrative of scripture shows God’s love for His creation through Christ, ultimately exemplified at the cross (Romans 5:8). Furthermore, if we consider passages like 1 Timothy 1:15, where Paul states that Christ Jesus came into the world to save sinners, we see confirmation that the essence of the Gospel is to rescue those who recognize their brokenness and need for forgiveness.
