In today's Gospel reading from Mark 13 at Mass, Jesus talks about end times and his Second Coming. He came to us 2,000 years ago. I intuitively know that he will come again to bring all things on earth to a close, for God's justice must reign. I cannot imagine that God will leave us hanging on our own forever. Besides, our planet earth is of limited size ~ are we to believe that it's meant to be our permanent home? Say we were placed upon a small planet only a mile in diameter, how long would we last with a growing population? The earth is a lot bigger, but it's still finite in size. So the question of Jesus' Second Coming is only a matter of when, not whether.
