Did I ever say anyone who lives in Scriptural darkness is Holy. If I did, then I apologize, it was not my intent. This does not change that light of truth was not present. It just was not understood and shone in darkness.
The implication of believing everyone has the Holy Spirit living in them is a denial of Scripture which states clearly that mankind is inherently sinful. Which is it for it cannot be both? Either man is inherently wicked, as Scripture states, or inherently “good” because he is indwelt automatically at birth with the Holy Spirit. Besides being a contradiction to Scripture, this latter is a spiritual impossibility because we know from Scripture that demon possession is real. A body cannot be both indwelt with the Holy Spirit and with a demon. It is a spiritual impossibility. One can have either — but not both. You keep citing Scriptures about “light” and “God’s light” and, forgive me, but it does sound as though you are equating that with a New Age type “God lives in all of us; we are all Heaven-bound” universalism. Scripture not only does NOT teach this but it teaches the exact opposite. NO WHERE in Scripture does Christ speak of giving the Holy Spirit to anyone except in the context of being one of HIS. The whole world does not get the Holy Spirit by some sort of “default”. We know this from the fact that Christ reiterates over and over and over again that “narrow is the way” to Him. The Holy Spirit is the mark of the believer — not some special “light” given to everyone. It’s the mark God places on those who know Him. It happens upon regeneration of the Hell-bound sinner (which describes all of us upon birth).
