About Peter DeHaan
Books by Peter DeHaan
Isaiah is a prophet in the OldTestament of the Bible. He is called a major prophet, along with Jeremiah, Ezekiel, and Daniel. This classification doesn’t mean they’re more important than the twelve minor prophets. This designation is because their books are much longer than those of the minor prophets. In fact, at sixty-six chapters, the book of Isaiah is the second-longest book in the Bible, trailing only Psalms with its 150 chapters.
Isaiah’s dad is Amoz. TheBible tells us nothing about Amoz other than he is Isaiah’s father, which it does often. Isaiah’s public career as a prophet spans several decades, during the reigns of four kings of Judah: Uzziah, Jotham, Ahaz, and Hezekiah. Isaiah is a contemporary of the prophets Amos, Hosea, and Micah.
During Isaiah’s ministry, Assyria conquered Israel (sometimes called the NorthernKingdom) and relocated the people. Judah (sometimes referred to as the SouthernKingdom) is all that remains of God’s people. Babylon will later conquer them. Isaiah warns the people about this, but the conquest doesn’t happen during his ministry.
Many of Isaiah’s prophecies consider God’s people in the near term, but other prophecies look forward several centuries to the coming of Jesus, as well as John the Baptist, who precedes Jesus. TheNewTestament quotes many of Isaiah’s words, making him a favorite prophet of many people.
There are two notable occurrences. First, when Jesus reads Scripture in the synagogue, he reads a passage from Isaiah, which prophetically looks forward to the coming Savior. ThenJesus proclaims himself as the fulfillment of that passage. How bold and unexpected—and fully appropriate.
Another notable NewTestament story is the Ethiopian eunuch. As he reads from the book of Isaiah, Philip approaches him and explains the meaning of Isaiah’s prophecy about Jesus. TheEthiopian man believes in Jesus, and Philip baptizes him.
Even centuries after Isaiah died, his words still influenced others, just as they can influence us today.
While we may not have the influence of Isaiah, what can we do to influence people during our lifetime and even after we’re gone?

Stop bringing meaningless offerings! Your incense is detestable to me. NewMoons, Sabbaths and convocations—I cannot bear your worthless assemblies. Isaiah 1:13
In addition to giving the people a bunch of rules—things they should and shouldn’t do—the OldTestament teaches two primary ways to worship God. One is through sacrifices, and the other is by a series of annual celebrations and festivals. Both forms of worship stand at the center of Jewish religion, and the Hebrew society revolves around these practices.
Yet God is not pleased with their worship. The book of Isaiah starts by recording God’s words of criticism for his people’s religious practices, calling their offerings meaningless. He takes no pleasure in what they give.
Why? Because the people offer their sacrifices with bad attitudes and wrong perspectives. Their approach to God is off. Their sacrifices don’t honor him. Instead, they dishonor him.
What God intended as a way to connect his people with him has the opposite effect. It drives a wedge between him and them. And they don’t realize it. They’re going through the motions, but as far as God is concerned, it’s meaningless activity.
Then God launches into criticism of their various celebrations. He goes as far as to say that he hates their practices. The way his people approach these festivals burdens God and wearies him. Because of their wrong approach, he has even stopped considering their prayers. He closes his eyes when they lift their hands in prayer and doesn’t listen to their words. All of this is because their worship is off base.
What does God want instead?
He doesn’t ask for sacrifices or seek a better observance of the religious holidays he mandated. Instead, he wants practical action. He tells them to wash up and get spiritually clean. They must stop wronging other people and pursuing evil that disgraces God. Rather, he wants them to do right. This includes to seek justice, defend the oppressed, and help widows and orphans.
God’s criticism of his people’s worship comes out as a harsh rebuke.
I wonder how he views our worship today. Does he regard our offerings as meaningless and our assemblies—our church services and religious holidays—as worthless? I want to say no, but I fear the answer is yes. God forgive us. May we do better.
Do we approach God with the right attitude? Is he pleased with our worship or irritated by it?

In that day the Branch of the Lord will be beautiful and glorious, and the fruit of the land will be the pride and glory of the survivors in Israel. Isaiah 4:2
Isaiah looks forward to the day when the Branch of the Lord will appear. Branch, with a capital B, is a euphemism for Jesus, who will come to rescue God’s people. Isaiah says this Branch will emerge as awesome and full of wonder, which is an understatement considering all that Jesus did, is doing, and will do. Jesus will produce fruit for the people. They will take pride in what the Branch produces and glory in it.
Jesus, the Branch—our Branch—will come for us, spiritually feeding us with his fruit: beautiful, wondrous fruit, the source of pride and glory.
Just as Jesus is theBranch, we are his branches, that’s branches with a lowercase b. We are branches connected to the Branch (which John calls the “true vine”). But being a branch connected to theBranch isn’t enough. Having a mere connection with Jesus is insufficient. When we’re connected with the Branch of Jesus, we must bear fruit. And we must produce good fruit. That’s what FatherGod, our Papa, expects from us.
If we produce no fruit, God, our gardener, will cut off our branch. Yikes! He’ll lop us off. We’re not worthy of remaining connected to Jesus if we produce no fruit—if we accomplish nothing for him. That’s a sobering truth. Having a connection with Jesus isn’t enough if it produces nothing. We can’t pledge our allegiance to him and then coast through life unchanged. He expects us to produce fruit because of our connection to him.
To further the analogy, every branch that produces fruit will eventually face pruning. This isn’t punishment. Instead, it’s a beneficial process that will allow us to produce even more fruit. While an untrimmed tree will yield some fruit, a tree pruned properly will produce much more. God, our gardener, will prune us so that we can make even more fruit for him.
But to do this we must remain with God, connected to Jesus, and bearing fruit. Else we risk him cutting off our branch, throwing us into the fire, and having the flames consume us.
Are we producing fruit through Jesus and for Jesus? Are we willing to let God prune us so we can produce even more?
[Discover more about Jesus as the Branch in Isaiah 11:1, Jeremiah 23:5, Jeremiah 33:15, Zechariah 3:8, and Zechariah 6:12. Discover more about us as branches in John 15:1–6.]
Then I heard the voice of the Lord saying, “Whom shall I send? And who will go for us?” AndI said, “Here am I. Send me!” Isaiah 6:8
Isaiah has a vision. He sees into heaven where God sits exalted on his throne. It’s grand, glorious. His flowing robe fills the temple. Seraphim—heavenly beings with six wings—fly above God in continuous worship of their Creator. They sing, “Holy, holy, holy.” This is not a gentle, reverent chant. Instead, it’s bold, thunderous, echoing. Their voices shake the temple. It fills with smoke.
God’s glory overwhelms Isaiah. “Woe is me,” he groans. He recognizes his mistakes, his sins, his words spoken in error. Full of guilt, he trembles in fear before a perfect God. Isaiah feels ruined by his shortcomings.
But God doesn’t leave Isaiah quaking in his unworthiness. Instead, an angel symbolically purifies Isaiah’s lips, taking away his guilt and redressing his mistakes. Isaiah is ready, now poised to speak before holy God.
But before Isaiah can say a word, God speaks. “Who can I send? Who will go as our messenger?”
It’s not that God doesn’t have anyone to send. It’s that he hopes Isaiah will volunteer.
Isaiah does. As if raising his hand, jumping up and down, Isaiah shouts, “Send me, God! Please, send me!” It’s like, with the game on the line, Isaiah says, “Put me in, Coach. I can do it!”
That’s exactly what God wanted. ThenGod gives Isaiah a message for the people. It’s a difficult one—a warning about hearing but not understanding, about seeing but not perceiving, about the hard hearts of a calloused people who don’t comprehend God’s ways. But if they can hear and see and understand, then they can turn to God and receive his healing.
It’s a message for the people then, and a message for us today: turn to God and receive healing.
Just as Isaiah says, “Send me,” Jesus says, “I’m here, Dad, ready to do your will.” Jesus comes to earth to be the ultimate sacrifice and redress the things we do wrong. He dies and then overcomes death so that we can live again. Jesus is why we can turn to God and receive healing.
Thank you, Jesus, for saying yes to Papa.
Are we ready to do what God asks us to do?
[Discover more about Jesus’s willing sacrifice in Hebrews 10:5–7 and Psalm 40:6–8.]
And they were calling to one another: “Holy, holy, holy is the LordAlmighty; the whole earth is full of his glory.” Isaiah 6:3
In Isaiah’s grand vision, he sees seraphim worshiping God in heaven. They fly above him, whooping, “Holy, holy, holy is the LordGodAlmighty. Earth is full of your glory.”
Does this sound familiar?
In another vision, this one in the NewTestament, John also has a supernatural encounter. It’s an epic revelation. John also sees into heaven. Four living creatures with six wings worship God continuously. They also proclaim that God is “Holy, holy, holy.” Then they confirm his eternal nature as being past, present, and future.
These are the only two instances in the Bible that the word holy repeats three times. Why three? For emphasis. AffirmingGod as holy stands as a true statement. Saying that he is holy, holy doubles the impact. But to make sure we don’t miss the point, Isaiah’s and John’s visions emphasize God’s holiness threefold. That way we won’t overlook it.
Holy is the only word that’s repeated three times in succession in the Bible. It’s a reference to God’s nature. May we never forget to worship God as our holy, holy, holy, glorious, eternal, and almighty God.
What does it mean to us to have a God who is holy, holy, holy?
[Discover more about worshiping God as holy in Psalm 99:9, Romans 12:1, Revelation 4:8, and Revelation 15:4.]
Again the Lord spoke to Ahaz, “Ask theLord your God for a sign, whether in the deepest depths or in the highest heights.” ButAhaz said, “I will not ask; I will not put the Lord to the test.” Isaiah 7:10–12
God speaks to KingAhaz through Isaiah: “Ask me for a sign, anything. Nothing is too hard or too grand.”
But Ahaz refuses. “I will not ask for a sign,” he says. “I will not test God.”
Did Ahaz answer wisely or foolishly?
Other people in the Bible sought a sign from God. WhenGideon asks, once is not enough. He does it twice in a row. God promised to save Israel through Gideon. ButGideon doubts God
