This came up as part of my reading today. 2 Samuel 14
14 All of us must die eventually. Our lives are like water spilled out on the ground, which cannot be gathered up again. But God does not just sweep life away; instead, he devises ways to bring us back when we have been separated from him.
It is in the story of Absalom after he had killed his step brother Amnon over the rape of there sister. You can read it in your bible.
In this part of the story later on, Joab knows that David, father and king, wants his son back from exile, but his honor will not allow it.
This passage echoes the way God wants to bring us all back into His family, He has devised away to do that through His son Jesus. He arranged it so that if we follow Jesus we can be forgiven our sins and seen by God as innocent of all. Then we can approach the throne of the king again.
