How does the doctrine of total depravity relate to salvation?

The doctrine of total depravity, a key element of Reformed theology, asserts that every part of humanity is affected by sin, rendering us incapable of achieving righteousness or contributing to our salvation. This foundational belief underscores the necessity of grace for salvation, as articulated in Ephesians 2:1-3, where Paul describes the unregenerate state of humanity as dead in trespasses and sins. Understanding total depravity leads us to recognize that we cannot justify ourselves through works, as Romans 3:10 states, 'There is none righteous, no, not one.' Consequently, it is only through God's sovereign grace, as, expressed in the doctrine of unconditional election and limited atonement, that we can be saved, highlighting the importance of faith in Christ as the sole means of justification.
