The development of this apocalyptic phrasing of hope has been traced too often to require long rehearsal here. If the Greeks were essentially philosophers and welcomed congenially ideas like endless cosmic cycles, the Hebrews were essentially practical and dramatic in their thinking and they welcomed a picture of God's victory capable of being visualized by the imagination. At first their national hopes had been set on the restoration of the Davidic kingdom; then the Davidic king himself had grown in their imagination until, as Messiah in a proper sense, he gathered to himself supernal attributes; then, as a child of their desperate national circumstances, the hope was born of their Messiah's sudden coming on the clouds of heaven for their help. Between the Testaments this expectation expanded and robed itself with pomp and glory, so that when the Christians came they found awaiting them a phrasing of hope which they accepted to body forth their certainty of God's coming sovereignty over all the earth. This expectation of coming triumph was not progressive; it was cataclysmic. It did not offer the prospect of great gains to be worked for over long periods of time; it offered a divine invasion of history immediately at hand. It was pictured, not in terms of human betterment to be achieved, but of divine action to be awaited. The victory would suddenly come like the flood in Noah's day, like the lightning flashing from one end of the heaven to the other, like a thief in the night.
