It's been something that I've thought about for awhile. I am studying on renewing the mind, which inevitably leads me to Scriptures about the heart, will, soul, etc...
This is a part of my endeavor to "rightly divide the word of truth." The concordance I mentioned is giving me some insight. Thanks again.
