Why is it impossible for man to save himself?

Scripture consistently reveals that all have sinned and fall short of the glory of God (Romans 3:23). This inherent sinfulness prevents anyone from achieving righteousness through their own efforts. The rich young ruler exemplifies this truth, as he could not give up his possessions to follow Christ. Jesus highlighted that with men, salvation is impossible because true faith and obedience can only come from God’s enabling grace. This reality emphasizes the need for redemption through Christ and the necessity of God's initiative in the salvation process.
