Baruch 4:17-20. Baruch is comparing Jerusalem and God's law that dwells there to a mother mourning her children in exile. "But I, how can I help you? " She asks. The only one who can deliver them is "He who brought these calamities upon you." So, she says, "Go my children, go; for I have been left desolate. I have taken off the robe of peace and put on the sackcloth of my supplication. I will cry to the Everlasting all my days."

Mothers do realize, sometimes, that there is nothing more they can do to help their child. It is heartbreaking, but it is also the moment we realize that the only person who can save them is the one "who has brought all these calamities upon them", the one who is trying to let them see the error of their ways by allowing them to suffer. And so it really is the most loving thing to do to let them go and to just pray for them. God has a plan for them, we must let Him carry it out, even if it means we watch them suffer, as hard as that is to do. Just think of Mary watching Jesus' passion. And think of how she intercedes for all of us constantly, with a mother's total love, but often she has to watch us suffer as well.
