What Stands the test of time?

I had the observation that there were things of antiquity that have stood the test of time, while other things have not done so well -- either by the forces of nature or the forces of humanity. On several occasions, wonderful examples of faith have stood for these centuries, while near by grander and more glorious structures have very little left.
From Ephesus here is an example. The probable humble tomb of St. Luke (probably the Apostle) stands while just two or three miles away, all that remains of the grand temple to the God Artemis (which was at least twice as large as the great Parthenon in Athens) is a single pillar upon which a stork has made a nest. And it is now in a swamp.

Of course, the Gospel of Jesus Christ carried by Paul and the Apostles did not have any stone monuments or temples. All it has was the living witness of disciples across the centuries. This Gospel is still full of power and witness.

Part of my reflections on this line of thinking has been related to thinking about the foundations of my faith and witness, and how the ripples of the discipleship of contemporary witnesses will stand the test of time.
