I believe, and hold it as the fundamental article of Christianity, that I am a fallen creature; that I am of myself capable of moral evil, but not of myself capable of moral good, and that an evil ground existed in my will, previously to any given act, or assignable moment of time, in my consciousness. I am born a child of wrath. This fearful mystery I pretend not to understand. I cannot even conceive the possibility of it, - but I know that it is so. My conscience, the sole fountain of certainty, commands me to believe it, and would itself be a contradiction, were it not so - and what is real must be possible.
