The wonder of the gospel is that God fulfilled what was spoken of long ago, accomplishing His purpose and plan, even in the midst of man’s failure to recognize it, and this is what we see spoken of by Isaiah in our text today. In this passage, Isaiah speaks of the mysteries of God’s plan. He declares his faith in God’s promise. He calls out the gloom and the darkness of sin. And he presents us with the hope of God’s promise to break that gloom through Christ the King.
