Luke 19:41 And when he was come near, he beheld the city, and wept over it,
The loud Hosannas to the king, faded in the distance, the clothes and palm branches are still behind him as he looks forward to accomplishing his final work on the cross. He must go to Jerusalem and he was now there. He looked over the city with tears falling from his eyes.
Luke 19:42 Saying, If thou hadst known, even thou, at least in this thy day, the things which belong unto thy peace! but now they are hid from thine eyes.
Jesus was their peace, the peace of Jerusalem, but they would not come to him, for they could not really see who the Messiah was or what he had come to do.
Luke 19:43 For the days shall come upon thee, that thine enemies shall cast a trench about thee, and compass thee round, and keep thee in on every side,
Luke 19:44 And shall lay thee even with the ground, and thy children within thee; and they shall not leave in thee one stone upon another; because thou knewest not the time of thy visitation.
He looked to the near future, the destruction of Jerusalem and her people, why? Because they had missed the visitation of their savior. They would reject God's best, their salvation and had chosen unbelief, following blindly the power of satan, rather than the power of God. Who do we follow? Are there sorrows in our life? Is it because we have listened to another voice and followed the power of satan? Listen with spiritual ears to the voice of Jesus, calling you back to his peace and a sound mind.
John 14:27 Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid.
