My heart is genuinely broken over losing this person. How does God heal something like that?

“He healeth the broken in heart, and bindeth up their wounds.”

This psalm was sung by people returning from exile to a wrecked city, and the same song that praises God for counting and naming the stars says he binds up wounds. The Hebrew is medical, the language of setting a broken bone. Healing here is not a mood that descends. It is slow, deliberate work done on something genuinely broken, by someone who does not consider your grief too small to attend to.

“Blessed be God, even the Father of our Lord Jesus Christ, the Father of mercies, and the God of all comfort; Who comforteth us in all our tribulation, that we may be able to comfort them which are in any trouble, by the comfort wherewith we ourselves are comforted of God.”

Paul had been through something in Asia so severe that he says he despaired even of life, and out of that he writes about the God of all comfort. The comfort he describes is not an explanation and it does not arrive early. It arrives inside the trouble rather than instead of it, and it eventually turns outward, because the people who comfort best are usually those who have been through it.
