Even Christ's words have been heavily edited.  I believe that He allowed this to happen because He wants us to look to Him first, and then to the written word to confirm matters.  It is written that God gives us our instructions in our sleep.  Then there are visions, miracles, and the many gifts of the Spirit, to show us what He meant by what He said ... or even said such at all.
I believe that the Bible is our "road-map", which reveals God, and the path to Him to us, but it isn't the actual path, just a picture of it.  Like the yellow lines and guard-rails ... we travel within those guides, those boundaries, but they aren't the road-way under our tires.
Walking with Christ is considered by many to be just a figure of speech, but maybe it is more real than we would suppose.  If you believe in a "living" God, then is it too far fetched to expect Him to personally guide you now and then?  To personally clue you in on important matters, when you really need to know?
