The Gospel today speaks of a prediction that Jesus makes about the destruction of the temple. It was if someone was able to predict the destruction of the twin towers all the way back in 1971. When the destruction of the temple did occur approximately forty years after Jesus' death, it was yet another sign of His authenticity.
Jesus also properly predicted that there would be false messiahs after him that would promise that Israel's liberation through revolution and war. In fact, these messianic militaristic zealots, were part of the cause of the destruction of the temple because by their violence they provoked the Romans to even greater violent reaction culminating in the destruction of the temple in 70 A.D.
In contrast, Jesus' way was the way of non-violence. He warned His disciples that they would face persecution, imprisonment and even death. Remarkably, approximately 240 years after the destruction of the temple, Rome itself would convert to worship the Jewish God as their Father by being baptized and by consuming the Body and Blood of Jesus when Christianity became the official religion of the Empire in 313 A.D.
In our own day as in the days of the early Christians, we can be intimidated by news of wars, insurrections, Church scandals, impeachments, civil unrest, plagues, etc. In the midst of all of this bad news, Jesus gives us news that is good. Out of the chaos of this world, Jesus Himself will give us the gift of His wisdom, the Holy Spirit, to guide us through whatever trials and tribulations afflict us. While the details of the future remain opaque, our mission in the present remains clear: we must persevere in prayer.
