The prophecy is Isaiah 9 looks not only to the first coming of the Messiah but his second advent as well. He will come as a child and redeem his people but he will also come again, establishing his kingdom which will last forever and ever.
Waiting isn’t easy. In fact, it’s one of the toughest things we have to face. Waiting is especially hard when we’re in the darkness. Israel waited for a long time for the coming of her redeemer. But God’s promises did not fail. At the right time, the light dawned. What can the Christian learn from this? God’s promises never fail, come at the right time, and are always based on his being and fulfilled in his Son!
