The God portrayed in the Hebrew Scriptures and in the life of Jesus is not only extraordinarily different, but diametrically opposed to other visions. This is not to say that there are no truths in other religions, or that they bring no insight to life; but, in them, one does not discover the fullest self-revelation by God. After all, if this is truly God we are talking about, then it seems to me that we are fully dependent upon what he lets us know about him, and all of our other speculations are likely to be wide of the mark, if they are not grounded in what he has given us.
