It's All In The Dirt

We always talk about this parable as a story about the sower when it is a story about the soil and the Kingdom of God.  Over the years we have had large vegetable gardens and can personally testify to the value of good dirt.  One time we planted jalapeño peppers in my father in-law's garden.  Everything grew well in his garden but these had NO heat to them at all.  Was it a bad set of plants or was it something in his dirt that affected them?  Scientifically I have no proof but the following year were able to plant them in our own garden and we had hot jalapeños!  Good soil can affect everything.
