Of course, when it is said that man is totally depraved, this should not be taken to mean that people never do anything positive or good, or that one is always as bad as he could possibly be. All people occasionally do things that benefit others. A person may do some outwardly good deed, but deep in his heart there is some motivating factor that serves the self. He does the good deed because it is expedient for himself at the time. Thus, for a deed to be truly good, in an ultimate sense, one's motives must also be good.
Motivation is the crucial point at which everyone fails.
A man is said to be good relative to other men. For example, compared to Adolf Hitler, it would be fair to say that Winston Churchill was a good man. However, the Bible speaks of goodness relative to God. So, the Biblical view of Fallen Man is that he exists in a state of moral corruption. His whole being is inclined toward sin so that he is unable, in his own power, to please or know God.
