Our Lord Jesus Christ made this prophecy in the gospel today. Still within the Church's lesson plan of teaching us about justice and mercy of God. Everything will be accounted for. Since the Jerusalem rejected her Redeemer in Jesus Christ and murdered Him, she would be destroyed to the ground. Her precious Temple would be razed to the ground. Justice will be served. But we should not forget that God's mercy will be manifest too in the end, in that those who accepted our Lord and Savior and followed Him will be rewarded.
