Ahaz is weary of prophets getting in the way of his politics and so even the offer of a sign as high as the heavens and as deep as Sheol can’t get him to swallow his pride and ask the God of Israel for help. God wearied by Ahaz’s feigned piety offers a sign anyway, a sign that Matthew will apply to Jesus though Isaiah was most likely speaking of Hezekiah, neither of which are named Immanuel, by the way, but then that is the way of prophecies. They point to a truth larger than the literal one and the same word that finds fulfillment in Hezekiah and Jesus finds fulfillment in our everyday. Immanuel, God with us is the point of the promise. God with us when we go our own way, choosing the evil and refusing the good. God with us when we feed ourselves with false promises and illusory hopes. God with us for the day when we tire of wearying God and turn again to the promise as high as the heavens and as deep as Sheol and recognize that the hope of God with us is that we would choose to be with God. Amen. Come, Lord Jesus.
