Micah is speaking to a people in crisis. They were under siege (5:1), a punishment that Micah thought they deserved (3:12).
He tells them that God is going to send a representative to rescue them and continue to care for them.
Yes, the OT God that we so often hear spoken of disparagingly is one who promises to save people who may not deserve being saved.
Furthermore, this savior is not a warrior but a shepherd, as Micah puts it, one of peace (5:4-5).
When we think about being rescued, are we hoping for a shepherd?
