A promise given during the threat of war surprisingly became a beacon of eternal hope. The promise was originally given to an evil king of Israel. However, his descendant Joseph saw the fulfillment of the promise seven hundred years after it had been spoken. The original promise seemed out of context at the time but only made sense hundreds of years later with the birth of Jesus. I wonder if Joseph understood that the word given to his great, great, great, great, and many more greats grandfather was being fulfilled in his day. Matthew, the gospel writer, knew. He put the pieces together that were hundreds of years apart. One stemmed from unbelief, the other chose to believe. Joseph, unlike his ancestor Ahaz, acted in faith and experienced the answer to the promise.
Matthew 1:18-24
This is how the birth of Jesus the Messiah came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be pregnant through the Holy Spirit. Because Joseph her husband was faithful to the law, and yet did not want to expose her to public disgrace, he had in mind to divorce her quietly.
But after he had considered this, an angel of the Lord appeared to him in a dream and said, “Joseph son of David, do not be afraid to take Mary home as your wife, because what is conceived in her is from the Holy Spirit. She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins.”
All this took place to fulfill what the Lord had said through the prophet: “THE VIRGIN WILL CONCEIVE AND GIVE BIRTH TO A SON” (which means “God with us”).
When Joseph woke up, he did what the angel of the Lord had commanded him and took Mary home as his wife. (emphasis mine)
The promise fulfilled was about Immanuel. This promise was given to the ancestor of Joseph, a king of Israel named Ahaz. The hopeful promise came during an unlikely time in the midst of potential war. King Ahaz was afraid.
Isaiah 7:1-2
When Ahaz son of Jotham, the son of Uzziah, was king of Judah, King Rezin of Aram and Pekah son of Remaliah king of Israel marched up to fight against Jerusalem, but they could not overpower it.
Now the house of David was told, “Aram has allied itself with Ephraim”; so the hearts of Ahaz and his people were shaken, as the trees of the forest are shaken by the wind.
War was on the horizon. The people and the king were shaking with fear. The Lord told the prophet Isaiah to go and deliver a message to Ahaz.
Isaiah 7:4, 7, 9b
Say to him, ‘Be careful, keep calm and don’t be afraid. Do not lose heart because of these two smoldering stubs of firewood—because of the fierce anger of Rezin and Aram and of the son of Remaliah…Yet this is what the Sovereign Lord says:
“‘It will not take place,
it will not happen…
If you do not stand firm in your faith,
you will not stand at all.’”
Isaiah assured King Ahaz that the enemy would not overtake them. And the Lord encouraged Ahaz to stand in faith, to believe what God had told him. The Lord even went on to give a further opportunity to build up faith in Ahaz for what He had already promised to do.
Isaiah 7:10-12
Again the Lord spoke to Ahaz, “Ask the Lord your God for a sign, whether in the deepest depths or in the highest heights.”
But Ahaz said, “I will not ask; I will not put the Lord to the test.”
It sounded spiritual but the truth was that Ahaz was defying the Lord. God commanded the king to ask for a sign. This sign was to be a visible reminder of the promise to come. Ahaz, however, was a wicked king. Isaiah saw through his spiritual pretense to his evil heart.
Isaiah 7:13-17
Then Isaiah said, “Hear now, you house of David! Is it not enough to try the patience of humans? Will you try the patience of my God also? Therefore the Lord himself will give you a sign: THE VIRGIN WILL CONCEIVE AND GIVE BIRTH TO A SON, AND WILL CALL HIM IMMANUEL. He will be eating curds and honey when he knows enough to reject the wrong and choose the right, for before the boy knows enough to reject the wrong and choose the right, the land of the two kings you dread will be laid waste. The Lord will bring on you and on your people and on the house of your father a time unlike any since Ephraim broke away from Judah—he will bring the king of Assyria.” (emphasis mine)
In the context of impending war, this promise made little sense. However, in the scope of time and history, God was declaring the time of the Messiah. It would be after the fall of these other nations as well as devastations of war from Assyria. It was a promise for a distant future. Yet, the Lord had Isaiah declare this promise to Ahaz because it would be his descendant, Joseph, who would finally receive the fulfillment of this word.
A promise given by the Lord is a promise kept. A wicked king could not stop a promise of God. Evil nations rose and fell, but God’s word took place just as He had said. Time passed by but the promise came exactly on time. What He says He will do, He WILL do. He promised that Immanuel would be with us and Immanuel was given to us. His promise is a guarantee. We can trust the words the Lord speaks into our lives because Immanuel, God with us, came just as promised, so we know all the promises He has spoken will be fulfilled.
