i don't believe, that knowing who will go to hell or heaven or the amounts of them, can be judged by no one but God.
however, by my observations, and by this verse of the bible:acts 17:11,
(that to continually search for the truth)
i have come to understand Satan (as i can understand it)relative to God in this way:
God made man, and God IS by faith, and man denied God, and lied to God. the lie caused God to doubt man, and doubt is poison to faith. so God cast doubt to the earth, but loved man still; that God created of himself. to reconcile man to himself, that sustains all by its faith, it must not be denied by man. and so God sent his own consciousness in the body of man, that lived in the world, but not of the world (or the ways of the world). by this act, the doubt of man and God(as when Satan speaks with God in job, "appears" exactly so) and the lies of the created doubt of God (Satan), are shielded by christ. who replaced doubt.
(you can understand this by observing your own doubt in your consciousness, which the voice of our reasoning is the conscious, which will make you feel bad for bad things and good for good things, or, perhaps the opposite)
so then, can God only accept those that will remove doubt, because any doubt is poison to the faith of God. how God has managed to allow mankind to exist this long being poison, i can only wonder.
but this is how i understand it by what i have observed to be the reality of God, and only can say that if you dispute it with me, i have no proof but my own reason by what i have read and understand, and ask that you also continually search scripture for the truth.
keep your mind from this way of enquiry, for never will you show that not-being is
