So in the final book of the Bible, the rule and reign of God is portrayed in cosmic dimensions. Jewish readers familiar with this imagery, of a blazing mountain being hurled into the sea, would readily understand the literary allusion to the triumph of God over all the hostile kingdoms of the world. We are, then, not to look for historical accounts of volcanoes or the like as fulfillments of this prophecy. Rather, the allusions are to far greater works of destruction in the collapse of every hostile force arraigned against the Lord. It is a figure of speech used before in such passages as Deut.
Idolatry is that which naturally springs up in the mind fallen man.
Again, idolatry is seen as the problem. What about organized religion and the stupidity of alliances with co-religionists, afraid that one day we shall wake up to find that atheism has ruled the world. That is a denial of Romans 1. 9. He was hurled to the earth, and his angels with him. Locusts wearing iron breastplates will ascend from the pit of hell.
