Last evening we discussed briefly an excerpt from this essay that Rick Saenz brought to our attention.  I think it is well worth your time and reflection. Let me also recommend this youtube video by the same author, Philip Kenneson.  Dr. Kenneson teaches at Milligan College, and is the author of Life on the Vine:Cultivating the Fruit of the Spirit (IVP).  Here is the Amazon link for the book if you are interested.
