We can all agree we are under siege by evil, but we may disagree on the source of said evil. Gematria seems to be a late sign or mockery of this infliction of evil upon us.
Perhaps the ultimate evil is man (666) and Satan is just a personification or demonic scapegoat (Azazel) of said evil.
I contend the evil is of satanic source and helped along by lesser demons and man. How we confront those evils is of debate. I know of at least one person who seems under perpetual spiritual siege in his own ministry of exposing this phenomenon and helping provide deliverance. While he's not a part of any 'official' spiritual warfare taskforce or ministry, I was trying to gain some insight as to how we can all avoid the pitfalls of putting ourselves directly into harm's way. What/how is the right way to approach such a dilemma?
While doing a little research on gatekeepers/doorkeepers/shepherds/pastors and intercessors, I came across this article which resonated with me since I have been taking this specific approach for sometime (and I didn't even know it was a 'thing'):
