Today’s Bible reading looks back to Isaiah 7:14 and finds its fulfillment in Jesus. Did Matthew go too far in applying this prophecy to Jesus?
Isaiah 7:14’s context is that God extends to King Ahaz an unusual offer to ask for a sign. When he refuses, saying he doesn’t want to test God, Isaiah steps forward and gives the Isaiah 7:14 prophecy. He says that in the time it would take a young woman to be married and give birth to a child and for that child to come to the “age of accountability”, God would deliver His people from their Exile. In other words, God would fulfill Isaiah’s prophecy in about a decade.
So what’s the problem? Isaiah says God would provide this sign in just a few years. Yet Matthew says Isaiah’s prophecy was about Jesus, born of a virgin young woman, Who came on the scene several hundred years later. So who’s right Isaiah or Matthew?
They’re both right!
Oftentimes, the writers of the New Testament — and even Jesus Himself — will quote from or allude to a passage from the Hebrew Scriptures (their Bible) and find the fulfillment of that passage in Jesus and the New Covenant. In this particular instance, Isaiah uses the Hebrew word for young woman, not necessarily a virgin young woman. (Note: Hebrew has two different words for 1) a young woman and 2) a virgin. If Isaiah meant virgin, he could/should have specified virgin; instead he used the general term young woman.) Yet, Matthew clearly understands the passage as referring to a virgin, specifically Mary, a virgin, a woman who has “known no man”. (Luke 1:34) In fact, Matthew points out that Joseph keeps Mary a virgin until after Jesus is born. (Matthew 1:25)
Under the inspiration of the Holy Spirit, Matthew freely reads and applies Isaiah’s prophecy to Jesus, just as Peter applies Joel’s prophecy (Joel 2:28–32) to the Day of Pentecost. (Acts 2:17–21) In other words, even if Isaiah isn’t specifying a virgin in 7:14, Matthew sees that Jesus, born of a virgin fulfills the prophecy.
I said earlier that both Isaiah and Matthew are right. Under the inspiration of the Holy Spirit, Isaiah the deliverance of God’s people in a few years. He may have — but didn’t have to — see Jesus as the fulfillment. The prophecy was fulfilled in two ways: immediately, and several hundred years later.
Why make such a big deal about this? Because it matters! Critics say that Isaiah’s prophecy wasn’t fulfilled in Jesus because Isaiah used the word for young woman instead of virgin. This is a backhanded accusation that Jesus wasn’t born in a virgin birth. It’s an attack on Jesus. And it’s an attack on the reliability of the Bible.
But Isaiah didn’t have to know that virgin-born Messiah would be the fulfillment of His prophecy. The Doctrine of the Virgin Birth doesn’t live or die on Isaiah’s prophecy. The Doctrine of the Virgin Birth lives or dies on Matthew and Luke’s testimony and description of the unique conception of Jesus in Mary’s body.
How did it happen? All I know is what the angel told Mary and Joseph: The baby was from God. (Matthew 1:18, 20) The angel didn’t give Mary and Joseph “The Talk”. He just said Jesus had been conceived in a unique way. (Luke 1:35, 37) And the coming of Jesus would bring a new intimacy with God and mankind. (Matthew 1:23b)
The Bible is trustworthy. Don’t let the critics try to convince you otherwise. The Bible can stand up to the allegations and accusations of the critics. Every one of them has died and will die. But the Word of God will stand forever. (Isaiah 40:8)
