Jesus has foreknowledge of the destruction that is coming to Jerusalem in 70 AD. Roman forces will besiege and destroy much of the city, and Jesus has heartbreak for the devastation that will occur.
It's an important aspect of our faith to hold onto -- God weeps when destruction is visited upon God's people. God made the world and all that is in it, and it is all precious to God. In an age where we are bombarded by bad news from all over the world, it's easy to become numb to it. But God still feels pain for the tragic loss that occurs around the world. May we remember that and let it soften our hearts as we seek to follow Christ and love the world the way God loves it.
