How does the doctrine of total depravity relate to our understanding of salvation?

In sovereign grace theology, total depravity posits that every aspect of humanity is affected by sin, leading to an inability to earn salvation through good works or moral action. This doctrine is crucial as it establishes the need for divine intervention through grace for salvation, as presented in Ephesians 2:1-9. Without recognizing the severity of our fallen condition, one may mistakenly believe that they can attain God’s favor through personal merit. Salvation is solely by God's grace, highlighting that it is not our actions but God's sovereign decision to save that enables us to respond in faith.
