How do we know that all saints are sinners saved by grace?

The essential tenet that all saints are sinners is rooted in Scripture. Paul affirms in 1 Timothy 1:15 that Christ Jesus came into the world to save sinners, indicating that salvation is for the lost. This reflects the truth that no one can achieve righteousness by their own efforts; rather, it is through God's grace that we are saved. Furthermore, Paul irreverently calls himself the chief of sinners, pointing out that the grace extended to him serves as a pattern for others who would believe. Thus, all saints share the common experience of being saved from sin, demonstrating that grace is foundational to their identity as children of God.
