WHY DID JESUS HAVE TO BECOME HUMAN? (CHRISTOLOGY 2)

Last week, we began our journey through Hebrews by focusing on Christ’s divine nature. In just four verses, we saw that Jesus is the agent, purpose, sustainer, and ruler of creation. He is fully God—uncreated, eternal, and the exact expression of God’s nature. That was a lot of theology packed into a small space.

Today we slow down and move to Christology part two: Jesus’ human nature. This raises a crucial question for Christians then and now: Why did Jesus have to become human?

The theological term for this is the incarnation—the central Christian belief that the eternal Son of God took on human nature in the person of Jesus Christ. Importantly, Jesus did not stop being God when He came to earth. He retained His divine nature and added a fully human nature. This means Jesus is one person with two distinct natures: fully God and fully man. No other being in the universe exists like this.

While on earth, Jesus didn’t “turn off” His divine power. Instead, He chose not to exercise His divine attributes independently. He lived in complete dependence on the Holy Spirit. The early church called this mystery the hypostatic union. It’s deep theology, but the book of Hebrews doesn’t present it as abstract theory. It presents it as good news.

Let’s slow down and read our passage for the day:

Hebrews 2:14–18 (NLT)

Because God’s children are human beings—made of flesh and blood—the Son also became flesh and blood. For only as a human being could he die, and only by dying could he break the power of the devil, who had the power of death. Only in this way could he set free all who have lived their lives as slaves to the fear of dying…

From this passage, Hebrews gives us seven reasons Jesus had to become human.

First, Jesus became human because we are human. Since God’s children are flesh and blood, the Son also became flesh and blood. Only a human could represent the human race before God. To save humanity, the Savior had to belong to humanity. In God’s courtroom of justice, Jesus stands as our representative—one who truly understands our condition.

Second, Jesus became human so He could die. Death is the penalty for sin, established by God from the beginning. This is the great paradox of the gospel: the Author of life became mortal. If Jesus had remained only divine, He could not have died—and if He could not die, we could not overcome death. Hebrews later reminds us that without the shedding of blood, there is no forgiveness of sins.

Third, Jesus became human so He could break the power of the devil. Hebrews says that through death, Jesus destroyed the one who had the power of death. Satan once held the authority to accuse humanity and hold eternal separation over our heads. Notice the tense—had the power of death. Through the cross, that authority was broken.

Fourth, Jesus became human to set us free from the fear of death. Death is still inevitable, but it no longer has the final word. In the ancient world, death was a constant companion, and fear of it shaped daily life. The Christian hope of resurrection transformed everything. As Paul later declared, “O death, where is your victory?” Christians don’t have to live as slaves to fear anymore.

Fifth, Jesus became human so He could be our high priest. A priest bridges the gap between a holy God and broken people. Jesus had to be made like us in every respect to fulfill this role. He is merciful toward our weakness and faithful toward God’s holiness. Hebrews will return to this theme again and again.

Sixth, Jesus became human so He could be our sacrifice. In the Old Testament, priests offered animals. In the New Covenant, the Priest is the sacrifice. This is the ultimate power move of grace: Jesus offered Himself to take away the...
