It isn't supposed to be this way

I came across this C.S. Lewis quote reading Dick Staub's latest blog entry on the meaning of lost:

No man knows how bad he is until he tries to be good…Only those who try to resist temptation know how strong it is…That is why bad people know very little about badness. They have lived a sheltered life by always giving in. We never find out the strength of the evil impulse inside us until we try to fight it: and Christ, because He was the only man who never yielded to temptation, is also the only man who knows to the full what temptation means—the only complete realist.

...we only know how bad we are until we try to be good...too true...too true...Lord have mercy.
