What does total depravity mean in Reformed theology?

Total depravity, as articulated in Reformed theology, indicates that every part of a human being—mind, will, emotions, and flesh—is influenced by sin. Ephesians 2:1-3 describes humanity as dead in their trespasses and sins, illustrating that apart from Divine intervention, no one can seek God or understand His ways. This doctrine highlights the need for grace, signifying that salvation is solely an act of God’s mercy and power, independent of human effort or merit. Without confronting our total depravity, one cannot grasp the necessity of the gospel and God's remarkable grace through Christ.
