How does the passage of time effect the Christian claim of a "second coming of Christ"?
Answer:
Time makes the Christian doctrine of a "second coming of Christ" lose all credibility. If Jesus promised to come back shortly and the disciples expected so strongly to see Jesus return and establish the kingdom of God and neither event occurred, for what can the church still hope? In essence, Christian theological speculations on the "second coming of Christ" represent nothing more than the systematization of a mistake.
No amount of Christian theological acrobatics will ever solve the problems engendered by the historical reality that a promised imminent fulfillment made two thousand years ago did not occur as expected by the New Testament. Simply stated, Jesus is never coming back, not then, not now, not ever.
