The gospel tells us that Jesus wept when felt Israel's rejecting Him in an acute way as he crested the summit of the mount of Olives on His way to Jerusalem. He was going to spend His last Passover there, readying Himself for His Passion and Death on the Cross. And so the Lord prophesied Jerusalem's absolute destruction and its Temple razed to the ground by the Roman armies under Titus in 70 AD. This is what they got for rejecting the Lord and Savior. All of this brings us to ask ourselves whether we reject the Lord somehow. The worst is to be indifferent to Him.
