Jesus predicted the destruction of the Temple which was the center of their society. It was a symbol of Judaism and everything they knew and believed. Yet, it was going to come down. Jesus told the disciples not to fear, but to persevere and they would secure their lives. Our faith is not in the current systems or structures but in the God who loves us and provides for us. Often we fear change around us because it signifies a loss of control or loss of what is comfortable.
