Another key similarity between revival and nuclear fission is a strange phenomenon that occurs right before the atom splits. The nucleus actually depresses. Scientists observe that the neutron bombardment which seemed to be changing the nucleus, now shows no sign of reaching critical mass.
Nothing seems to be happening.
That is also what happens right before a manifestation of God's glory. The revival core will be praying and sensing a rising tide of power and expectancy. All of a sudden, you hit a brick wall. The power is gone. God's presence seems to have lifted.
