I came across this while tag surfing. I think it is helpful. From www.extremetheology.com
Here we must be clear that the main point of Christianity is not our morality and goodness. This is, to be sure, the thing driving every other world religion from Judaism to Hinduism, Islam to Mormonism and even Atheism! All of these “ism’s” are pointing mankind to achieve more and be better, to climb the ladder of moral success and be a good person. But Christianity is different, it begins not with man’s goodness or potential goodness but rather with man’s wickedness. From the first chapters of Genesis until the Revelation given to St John the Bible is a record of mankind’s failure; it is a testimony of his sin.
You can read the rest here: Christian Hypocrites. This is certainly not to deny that along with Christian faith comes the progress in holiness (what we call sanctification), but even that, we must acknowledge, is a work of the Holy Spirit. Enjoy the essay.
