we do not have a sinful nature…
we have a brain that we programmed with a personality AI in our ignorance (no operators manual and our parents totally ignorant on spiritual matters) with addictions to all of our emotions and desires…
the program is always suggesting "sins" and since we personally programmed it with our favorite, most delicious emotions and bodily feelings and our favorite rationalizations for our behavior, it appears we are automatons of our own making…
but there is the greater power within of spiritual knowing that if heeded, breaks us out of the prison of our self-created addictions
