"By myself I have sworn, my mouth has uttered in all integrity a word that will not be revoked: Before me every knee will bow; by me every tongue will swear."
Now how would this prophecy be fulfilled? Certainly not through God's display of power, men are sick of other men abusing it. They will rather die than give in to a God abusing his power. All their life they suffered from their fellowmen because of it. But how will it be fulfilled that "every knee" will do it? Through mercy and redemption? We will see.
