Suppose, for the sake of discussion, that we could if good enough, smart enough, wise enough figure out exactly when the end will come and what will happen when it does. What would it gain us as individual and/or the church? I think that we, the people of God, have wasted a lot of time, money and energy trying to figure this out. What could the church, as the people of God, have done with all that money, brain power and energy have done for the Kingdom of God in the here and now "doing unto the least of these."
I once told the members of my Sunday School that I regarded all this speculation including the Bible verses that generate all this speculation as "Theological Pornography." Basing my comment on the Supreme Courts ruling that pornography is "that which is without redeeming social virtue." All of this has divided and sub-divided and split the subdivisions over and over again. It is detrimental to the public and private education of our children. It has made a mockery of the two great commandments given to us by Jesus-to love God first and always and our neighbors as ourselves. How can we love one another if we are screaming at each other that we are right and they are wrong about something that in the words of Jesus only God knows.
I would rather try to figure out a solution to the homeless problem or figure out how, in the richest nation on earth that produces more food than any other nation, provide enough protein to malnourished children to keep them alive and awake enough to profit from his or her free education. I could go on, but you get the idea. If you have not guessed already, my ThM is in ethics.
Jesus' first words in the Gospel of Mark were, "The Kingdom of God is at hand." We should be about the mission he gave us not trying to second guess God.
