These are the ruins of the synagogue that was built in Capernaum sometime three or four hundred years after the time of Jesus. It was the most magnificent building in town.  Rightly so, because it was the place where people came to try to draw close to God.  The idea was that the greater and more magnificent the building, the closer one could get to God.  That concept is still practiced today.  That synagogue  was probably built on the original foundation of an earlier synagogue that had fallen down, likely the one in which Jesus spoke the following words:

I am the living bread that came down from heaven. If anyone eats of this bread, he will live forever. And the bread that I will give for the life of the world is my flesh.”  (John 6:51)

This is the bread that came down from heaven, not like the bread the fathers ate, and died. Whoever feeds on this bread will live forever.”.  Jesus said these things in the synagogue, as he taught at Capernaum.  ​(John 6:58 — 59)

The bread he was referring to was Himself.  When you visit the synagogue you stand among dilapidated ruins.  You also can visit enormous, ornate, modern houses of worship and sometimes be standing among ruins.  Ruins, because in some of those places it is very tough to draw close to God in a lasting and meaningful way.  But when you come to Jesus by faith, you are filled with God’s presence in a continuing way, with His Fresh Bread of Life.
