God is such a wonderful and amazing God. He warns people (the Israelites), gives them time to reflect then repent, judges them when they don’t repent and then restores them. We don’t deserve His mercy but God is a God of love. He regathers, redeems and restores the remnant. Their response is to rejoice in their Redeemer.
My favorite verses are: “Zion, let not your hands be weak. The Lord your God in your midst, The Mighty One, will save; He will rejoice over you with gladness, He will quiet you with His love, He will rejoice over you with singing.”
Imagine God Almighty rejoicing over you with gladness and singing!
