Isaiah 28:21 Meaning: When God Does a Strange Work

Two Hebrew words carry the weight of this verse. The first is zar, translated as 'strange.' It means foreign, alien, something that does not belong to the usual order. The second is nokhriyah, also meaning foreign or alien. God uses both words to describe the work he is about to do. This is not his natural action. His natural work is mercy, patience, and salvation. Judgment is a work he does not delight in; it is forced upon him by our stubborn sin.

The phrase 'Yahweh will rise up' uses the Hebrew verb yakûm, which pictures a king standing from his throne to act. For a long time God had seemed to sit still while people mocked him. Now he stands. But even his standing is not what he wants. It is the last resort of a holy God who cannot ignore rebellion forever.

Christians have read this verse with different emphases. Reformed commentator John Calvin saw it as a terror for those who persist in sin: the same God who fought for his people will fight against them. Matthew Henry stressed that judgment is a 'strange work' God does not delight in; it goes against his merciful nature. In the Wesleyan tradition, John Wesley noted that bringing destruction on Israel was 'contrary to the benignity of his own nature.' Many Christians across traditions see in this verse a foreshadowing of the cross, where God did the strangest work of all: judging his own Son in our place. All agree that God's judgment, though real, is not his first desire.

Some read this and think God is inconsistent or arbitrary, that he changes his character and becomes cruel. In fact, the word 'strange' does not mean he acts out of character. It means judgment is not his preferred work. He is not a God who delights in punishing, especially his own covenant people. But because they stubbornly refused to turn back, judgment became necessary. His holiness and love do not contradict each other. His strange work is still his faithful work, done because he will not let sin have the final word.

If God's actions in your life ever feel strange, like nothing you expected from a loving Father, this verse offers a sober kind of comfort. It reminds you that judgment and discipline are not God's first choice. They are his unusual work. When life hurts, when consequences arrive that you tried to avoid, do not assume God has abandoned you or changed. His strange work is still his work. It is purposeful, holy, and always in service of his covenant love. This week, ask yourself honestly: is there sin I am holding onto that might force God to act in ways that feel strange to me? It is better to turn back before he must rise up.
