I believe the best way to answer that question, if we believe in a God of love, is to simply ask the question, would loving parents submit a child to eternal suffering or separation? For that matter, would any loving person even send a mad dog to such an eternity? My, how we have desecrated God and love!
I am always amazed at how parents are so afraid one of their children might get caught up in the world, become lost and be condemned by God. There is no way they would do such awful thing but they are afraid God might while at the same time claiming God’s love is much greater.
