What does the Bible say about the impossibility of salvation with man?

In Luke 18:27, Jesus emphasizes the impossibility of salvation through human effort, declaring, 'The things which are impossible with men are possible with God.' This assertion is rooted in the understanding that human nature is inherently sinful and unable to achieve righteousness or salvation on its own. The rich young ruler's encounter with Christ illustrates the futility of relying on personal merit or wealth for eternal life. No matter our status or accomplishments, we are all descendants of Adam, thus universally affected by sin. It is only through God's grace and sovereign intervention that we can be saved.
