What does the Bible teach about the inability of man to save himself?

Biblical teaching asserts that due to our fallen nature, no individual possesses the inherent ability to achieve salvation through their own efforts or righteousness. John 1:13 emphasizes that those who are granted the right to become children of God are not born of 'the will of the flesh, nor of the will of man, but of God.' This indicates that salvation is exclusively the work of God, initiated by His sovereign grace. Therefore, recognizing our inability to save ourselves is crucial for understanding the nature of redemption and inspires dependence on Christ alone for salvation. This truth upholds the doctrines of grace, reminding believers that it is by grace alone that they have been saved.
