Although judgment is coming to God's people, Isaiah prophesies of a time when light will pierce through the darkness and deliverance from oppression will come. This deliverance is promised and described in 9:1-7. He also tells us that this deliverance will come through a child, but a child who is the "mighty God." We celebrate the fulfillment of this promise in the coming of Christ and rejoice in the deliverance He brought.
