God is purposeful. If I were a member of Israel at the time I would have been anxious about the affliction and scattering. But by doing that God spread the knowledge of Himself throughout the world. Purpose. His Purpose.
There is purpose in what the Lord brings into our lives. We can trust Him with those. We can rest in His finished work, we can rest, relax and know that He knows what He is doing with us.
I need that reminder, pretty much daily.
