When have Christians been promised physical security? In the early Church it is evident that they did not even expect it! Their security, their true life, was rooted in God; and neither the daily insecurities of the decaying Roman Empire, nor the organized persecution which followed later, could affect their basic confidence. In my judgement, the description which Christ gave of the days that were to come before his return is more accurately reproduced in this fear-ridden age than ever before in human history.…When God decides that the human experiment has gone on long enough, yes, even in the midst of what appears to us confusion and incompleteness, Christ will come again. This is what the New Testament teaches. This is the message of Advent. It is for us to be alert, vigilant and industrious, so that his coming will not be a terror but an overwhelming joy.
