How do we know that only sinners can be saved?

The assertion that only sinners can be saved is deeply rooted in Scripture. Jesus' declaration in Luke 5:31-32 serves as a foundation, conveying that His mission was to heal the spiritually sick. Romans 3:23 confirms that all have sinned and fall short of the glory of God, establishing that everyone, regardless of their perceived righteousness, is in need of God’s grace. Salvation is accessed by recognizing one’s inability to meet God’s standards and turning to Christ, who alone justifies and redeems sinners through His sacrifice. Thus, only those who are aware of their sinfulness and need for salvation may respond to Christ’s call.
