little help w/ luther

quick question: somewhere i read a quote attributed to martin luther, the gist of which was that there are actually only two gods or two visions of god: one is a god that remains aloof and humans have to "climb up" to through good works or karma or whatever; the other god descends to humans w/ mercy and forgiveness. does that ring a bell w/ anyone? if it does, please leave me a comment w/ the quote or a cite or something. unless imagined it, in which case, uh, never mind.
