The Old Testament lesson for today (Isaiah 7:10-17) is the greatest example of how predictive prophecy often works. And in this case, it is not without its irony. Among the generally impious Kings of Israel and Judah, Ahaz stands out as maybe the most impious. The book of Kings records that “he even burned his son as an offering according to the despicable practices of the nations (2 Kings 16:3).” He personally offered sacrifices to various gods at the high places. And on a trip to Syria to meet the King of Assyria, Ahaz witnessed an altar in Damascus that he so fell in love with he sent his priest to get all the measurements. He then had the priests in Jerusalem built a replica, rip out the Altar of the temple and install his. He invited the King of Damascus down to preside with him over the inaugural offerings on the new altar. And he instructed his priests to do all their offerings on the new altar.
But for some reason God is not completely concerned about that blasphemous altar at this time. What he is demonstrating to Ahaz – the worst of them – is His faithfulness to his covenant with David, Ahaz’s lineage. The Northern Kingdom of Israel has aligned itself with Syria and is attacking Judah, the remains of the Davidic Kingdom. God sends Isaiah and promises Ahaz “don’t worry, have faith, they will not win, and within 65 years they won’t even be a nation.” And the prophet tells Ahaz to ask for anything he wants as a sign. “Let it be deep as sheol or as high as heaven (Isaiah 7:10).” What an opportunity! I can only imagine what I might ask for. But sticking with Ahaz’s unbelief, when the prophet of God tells him ask anything…Ahaz responds that “I will not put God to the test! (Isaiah 7:12).” Only Ahaz could multiply his impiety by being pious at exactly the wrong time. He’s quoting Deuteronomy 6:16 and Moses’ instructions to not be like Israel immediately after the Red Sea complaining that they had no water (Exodus 17) and that Egypt was better. But God is telling him to ask!
So even though Ahaz doesn’t believe, and won’t listen to the Word of the prophet and “wearies God” quoting scripture back to him, God is faithful. And through the prophet Isaiah delivers unto Ahaz a sign of that faithfulness. There will always be a Davidic King. In this immediate timeframe it is you – absolutely worthless Ahaz. “And the virgin shall conceive and bear a son…and before the child is a boy, the land of the two kings you dread will be deserted (Isaiah 7:14-16).” Imagine the impassioned prophet, and I always imagined Isaiah as someone who didn’t suffer fools gladly, of which Ahaz was a fool, imagine Isaiah pointing at some young lady at the royal court. And to them a child was born and a son was given (Isaiah 9).
That nearer fulfillment is like staring at mountains. You see the shorter mountains in front, but there are often greater mountains in the back. From a distance you can really tell how far off. There might be valleys between the peaks. As the nearer fulfillment was God’s sign about keeping his covenant with David, that there would always be a Davidic King, so also the greater fulfillment. And likewise the miracle of the greater fulfillment is much greater. In that still living Kingdom, one is lead to believe that the young lady conceived in the normal way. Crossing the valley of the years, Mary would conceive and bear a son, not in the normal way, but by the Holy Spirit. Not just a young woman, but the virgin. And the Virgin Mary’s son would be the eternal Davidic King. The child born and given to all of us. After long years, where even the heirs of David – like Joseph – probably chuckled at the claims, God is faithful. And unlike Ahaz, Joseph, with some angelic help, believes.
All the great prophecies, the signs and wonders of God, find their tallest peak fulfillment in Christ. Now we might often wonder what is beyond those peaks. The first advent points to the final advent. And we’d love to know the valley on the other side. But the sign of God keeps us focused on the mount – on Christ himself. Unlike Ahaz, have faith. “If you are not firm in faith, you will not be firm at all (Isaiah 7:9).” If the promise was good for Ahaz, it will be even more so for the man of faith.
