Then address, specifically, my contention about secondary intermediaries. Do they, or do they not, act under God’s command, and therefore have a will at one with His? If they do, then ... what is your point? If they are sent under God’s auspices, then it should be clear that they act with a view of bringing people to Him, not away from Him.
Your quoting of John 14:6 puts obvious Scriptural episodes of divinely-sanctioned mediation and your particular take on “coming to Jesus” in a rather startling - and completely unnecessary - opposition.
Don’t assume that everything that claims to be sent by God really is my friend.
