Total Depravity

"The Bible teaches the total depravity of the human race. Total depravity means radical corruption. We must be careful to note the difference between total depravity and "utter" depravity. To be utterly depraved is to be as wicked as one could possibly be. Hitler was extremely depraved, but he could have been worse than he was. I am sinner. Yet I could sin more often and more severely than I actually do. I am not utterly depraved, but I am totally depraved. For total depravity means that I and everyone else are
depraved or corrupt in the totality of our being. There is no part of us that is left untouched by sin. Our minds, our wills, and our bodies are affected by evil. We speak sinful words, do sinful deeds, have impure thoughts. Our very bodies suffer from the ravages of sin."
