[Sons to Glory!]

Now I think I got it. Thanks. I guess then it's a matter of what we think is unnecessary. I do agree, that even this conversation is perhaps along those lines. And for that matter, 90% or more of the discussions on this forum could be viewed that way, right? What justifies it is in the eyes of the justifier, or what glasses a person is looking through.

And you are right about Hebrews 4:12 - this verse is showing that we can't do it, and that it must be something of God beyond us that can do that dividing, namely His word. Without Him, we can't hope to divide our soul from our spirit on our own!
