i would, to an extent, both agree and disagree.
we both agree that not all peoples worship / believe in the same gods. and i agree that not all people are on the same path, nor will all lives be directed in such a way as to go down a specific path.
what is central to my concern, however, is whether the Allah of the Quran is the same as the Abba whom Jesus spoke of, and to. it *is* significant, exactly because Mohammad claims to be a valid and worth-listening-to mssenger of the same God whom Jesus loved and served and called "Abba".
if Mohammad claimed only to be amessenger of Allah and in no way connected Allah to the Abrahamic tradition, that would be fine and not so much of an issue. but because Mohammad claims Allah as the same diety as the God described in the Bible, it is really worth examinging whether or not the two messages (of Jesus and Mohammad) talk about the same god, and what kind of message that god imparts to humanity through these respective men.
