Lessons from Isaiah: God’s Sign to King Ahaz

“Then Isaiah said, “Listen well, you royal family of David! Isn’t it enough to exhaust human patience? Must you exhaust the patience of my God as well? All right then, the Lord himself will give you the sign. Look! The virgin will conceive a child! She will give birth to a son and will call him Immanuel (which means ‘God is with us’). By the time this child is old enough to choose what is right and reject what is wrong, he will be eating yoghurt and honey. For before the child is that old, the lands of the two kings you fear so much will both be deserted.”
Isaiah 7:13-16 NLT

Isaiah is frustrated with King Ahaz because he refuses to ask God for a miracle to save his country. Isaiah points out that Ahaz is not just testing the patience of human leaders but also God’s. But isn’t that like some people, who stubbornly stick to their sinful and selfish ways, even when they know that they are wrong, and ignore the advice or counsel about the right way? We have people today who choose a lifestyle that does them harm, physically and mentally, even though they know it is wrong, even admitting as such when challenged. But that was King Ahaz, and he probably knew the old Frank Sinatra song, “I’ll do it my way”, down to the last note. The second verse sums up Ahaz well, “I’ve lived a life that’s full / I traveled each and every highway / And more, much more / I did it, I did it my way“.

But Isaiah continued by giving Ahaz a sign from the Lord Himself. It is a famous verse, much used in the season of Advent, because it prophesies the coming of Jesus. A virgin having a child was a very rare event, and we marvel at such a prophetic foretelling of Mary and the Christmas story, something that has been a cornerstone of the Christian faith. But was there perhaps a second, more immediate, meaning for Ahaz that day? Isaiah explained how this sign from the Lord worked as a “timer” for the war. The boy would eat simple, everyday foods like “yoghurt and honey“. Before this child was old enough to know right from wrong (roughly age 12-13), the two kings threatening Judah, along with their lands, would be destroyed. This historical timeline was likely tied to a baby born during Isaiah’s time, providing immediate proof of God’s Word. 

We cannot leave these Scripture verses without turning to Matthew’s Gospel. A young peasant girl called Mary was engaged to be married, but “she became pregnant through the power of the Holy Spirit”. “Joseph, to whom she was engaged, was a righteous man and did not want to disgrace her publicly, so he decided to break the engagement quietly” (Matthew 1:19). But God had different plans and the account continues, “As he considered this, an angel of the Lord appeared to him in a dream. “Joseph, son of David,” the angel said, “do not be afraid to take Mary as your wife. For the child within her was conceived by the Holy Spirit. And she will have a son, and you are to name him Jesus, for he will save his people from their sins.” All of this occurred to fulfil the Lord’s message through his prophet: “Look! The virgin will conceive a child! She will give birth to a son, and they will call him Immanuel, which means ‘God is with us.’”” The same prophecy from Isaiah was quoted by Matthew, and we know the rest of the story, with Jesus, God’s Son, being born in a Bethlehem stable.

Did Jesus fulfil the next part of Isaiah’s prophecy, that “By the time this child is old enough to choose what is right and reject what is wrong, he will be eating yoghurt and honey”?. There is perhaps a fulfilment of this, because we know the event that happened when Jesus was twelve years old. He went missing at the time of the Passover festival and was found in the Temple speaking with the religious teachers. “His parents didn’t know what to think. “Son,” his mother said to him, “why have you done this to us? Your father and I have been frantic, searching for you everywhere.” “But why did you need to search?” he asked. “Didn’t you know that I must be in my Father’s house?” But they didn’t understand what he meant” (Luke 2:48-50). Was that the time when Jesus began to be aware of His mission, choosing what was right and rejecting what was wrong?

We pilgrims, with the benefit of hindsight, see how the Biblical prophecies were fulfilled and how foundational they were to the first coming of Jesus. We know that He will return again, and many prophecies apply to the event yet to come. But are we ready and prepared as prophecies work out in our lifetimes? Jesus said, “So you, too, must keep watch! For you don’t know what day your Lord is coming” (Matthew 24:42). Peter wrote, “But we are looking forward to the new heavens and new earth he has promised, a world filled with God’s righteousness. And so, dear friends, while you are waiting for these things to happen, make every effort to be found living peaceful lives that are pure and blameless in his sight. And remember, our Lord’s patience gives people time to be saved …” (2 Peter 3:13-15a). 

The question, “Are we ready?” hangs in the air and impacts every facet of our believing lives, day by day. We must do all that we can to be faithful to our calling.

Heavenly Father. Thank You for Your prophets and their messages of events yet to unfold. Help us to stay near the cross of Jesus so that we will be ready when the day comes, pure and blameless in Your sight. Amen.
