Actually, it is. By the very mention of "the Apocaplypse", the question is already a theological one (for lack of a better term). Spiritual might be preferable, in fact. The Apostle John saw some things 2000 years ago by being closely tied in with powers that are beyond our domain. He saw them from a perspective where, in the eternal realm, the end of history has already taken place, and the merging of time and eternity was about to begin. The one terminates and merges with the other.
People who do not believe these things, or those who have refused to treat them as genuine and therefore have not dealt with them, are nonplussed.
Those who are impressed by the prophetic are fascinated to see things that should not have been known by a man 2000 years ago, lining up right before our eyes.
Excellent comments.
Focus on God now and you will be guided.
