The Parabolic Universe: Parables explained

In part 3 of the mini-series about the parabolic universe, we're taking a look at some parables of Jesus, going from the simple to those that are seemingly impossible to understand.  These include the parable of the sower, the wise and foolish virgins, and the unfaithful steward.  What are we to make of these? This discussion is based off of my new book, The Parabolic Universe, a consideration of how God reveals Himself in nature.
