How do we know salvation is for those who cannot save themselves?

Salvation, by definition, is deliverance from sin and self, which inherently means it is for those who cannot save themselves. In the New Testament, particularly in passages like Romans 3:23-24 and Ephesians 2:8-9, we see a clear articulation that all have sinned and fall short of the glory of God, thus highlighting our complete inability to earn salvation through our own merit or actions. It is essential for Christians to grasp this truth, as it not only aligns with the character of God - who saves the unworthy - but also reassures believers that their salvation rests entirely on Christ's righteousness and not their own.
