Why does the Bible say we are not saved by our works?

Scripture asserts that salvation cannot be achieved through human works, as seen in Ephesians 2:8-9, which states that we are saved by grace through faith and not by works, lest anyone should boast. This doctrine highlights the absolute sovereignty of God in the act of salvation, showcasing that it is God who calls and justifies, not human effort (Romans 8:30). It underscores the lifeline of grace that every believer relies upon, allowing for no room for pride or self-righteousness before God. Rather, it promotes humility and dependence on the finished work of Christ for salvation.
