Are you teachable?

"Who is it he is trying to teach? To whom is he explaining his message? To children weaned from their milk, to those just taken from the breast?
For it is: Do and do, do and do, rule on rule, rule on rule; a little here, a little there."
Very well then, with foreign lips and strange tongues God will speak to this people,
to whom he said, "This is the resting place, let the weary rest"; and, "This is the place of repose"-- but they would not listen.
Isaiah 28:9-12 (NIV)
