Why Did Jesus Have to Die?

It is a fair question, and it deserves a real answer.

If God is all-powerful, why did anyone need to die at all? Could He not simply forgive? Could He not simply make everything right?

The Bible does not treat the cross as just another event. It treats it as the center of the whole story — the moment our sin was paid for, death was defeated, and the way back to God was opened.

But before we look at what Jesus’ death accomplished, we need to understand why it was necessary in the first place.

Why Was Blood Required at All?

The Bible gives a direct answer:

Romans 6:23 (NIV) — “For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.”

Wages are what you earn. Sin earns death — not as a random punishment, but because sin cuts a person off from the God who is life itself.

And forgiveness was never free of cost:

Hebrews 9:22 (NIV) — “In fact, the law requires that nearly everything be cleansed with blood, and without the shedding of blood there is no forgiveness.”

So there were only two ways this could end. Either we pay what we owe, or someone pays it for us.

Isaiah saw which one God chose, seven hundred years before it happened:

Isaiah 53:6 (NKJV) — “All we like sheep have gone astray; we have turned, every one, to his own way; and the Lord has laid on Him the iniquity of us all.”

Laid on Him. Our wrongdoing, placed on someone else.

Paul says the same thing, and puts it as sharply as it can be put:

2 Corinthians 5:21 (NIV) — “God made him who had no sin to be sin for us, so that in him we might become the righteousness of God.”

That is the exchange at the center of the Christian faith. He took what was ours. We received what was His.

Sin costs a life. That is what the blood is about. And God chose to pay that cost Himself. For centuries before the cross, He had been teaching His people what that would look like.

The End of Animal Sacrifices

Once we see that sin costs a life, the Old Testament sacrifices begin to make sense.

Leviticus 17:11 (NIV) — “For the life of a creature is in the blood, and I have given it to you to make atonement for yourselves on the altar; it is the blood that makes atonement for one’s life.”

A life for a life. That was the arrangement.

But it never actually finished the job. The priest offering the sacrifice was a sinner himself, and had to bring an offering for his own sins first (Leviticus 16:6). And the sacrifices never stopped:

Hebrews 10:1-3 (NIV) — “…Otherwise, would they not have stopped being offered? … But those sacrifices are an annual reminder of sins.”

Read that carefully. The sacrifices did not remove sin. They reminded people of it, every single year.

Then John the Baptist saw Jesus walking toward him and said:

John 1:29 (NIV) — “Look, the Lamb of God, who takes away the sin of the world!”

Not covers. Takes away.

Every lamb on every altar had been pointing to Him. And unlike them, His sacrifice never has to be repeated:

Hebrews 10:14 (NIV) — “For by one sacrifice he has made perfect forever those who are being made holy.”

Fulfillment of Prophecy

Jesus’ death fulfilled many Old Testament prophecies, proving that He was the promised Messiah.

Isaiah 53:3-5 (NKJV) — “He is despised and rejected by men, a Man of sorrows and acquainted with grief. And we hid, as it were, our faces from Him; He was despised, and we did not esteem Him. Surely He has borne our griefs and carried our sorrows… But He was wounded for our transgressions, He was bruised for our iniquities…”

Jesus’ death fulfilled the prophecy of a suffering servant, showing that God’s plan of redemption had been set in motion from the beginning of time.

But Isaiah was not the only one who saw it coming.

Centuries before crucifixion was ever used as a method of execution, David wrote this:

Psalm 22:16-18 (NIV) — “Dogs surround me, a pack of villains encircles me; they pierce my hands and my feet. All my bones are on display; people stare and gloat over me. They divide my clothes among them and cast lots for my garment.”

Pierced hands and feet. Soldiers gambling for His clothing. David was describing something he had never seen and could not have imagined, roughly a thousand years before it happened (Matthew 27:35).

Daniel adds something else — a deadline.

Daniel 9:26 (NIV) — “After the sixty-two ‘sevens,’ the Anointed One will be put to death and will have nothing. The people of the ruler who will come will destroy the city and the sanctuary.”

Note: In Daniel, a “seven” means a period of seven years. The verse before counts “seven ‘sevens,’ and sixty-two ‘sevens'” from the order to rebuild Jerusalem (Daniel 9:25). That is sixty-nine sevens, or 483 years. Counted from that order, many Christian interpreters find that it reaches the early first century, the time of Jesus, though the exact dates are debated.

Two things are worth noticing there. The Anointed One — the Messiah — would be put to death, not crowned. That is not what anyone was expecting of a coming king.

And it would happen before the city and the temple were destroyed. Jerusalem fell in AD 70. So the Messiah had to come, and die, before that day.

A New Covenant

There was one room in the temple that almost nobody entered. The high priest went in once a year, and no one else, ever. When Jesus died on the cross, something happened to that room:

Matthew 27:51 (NIV) — “At that moment the curtain of the temple was torn in two from top to bottom.”

This curtain separated the Holy of Holies — where God’s presence was — from the people. Notice which direction it tore. From the top down. No human hand could reach that high. God tore it open from His side. The old system of priests and sacrifices had done its work. Jesus had fulfilled it all.

Hebrews 10:19-22 (NIV) — “Therefore, brothers and sisters, since we have confidence to enter the Most Holy Place by the blood of Jesus, by a new and living way opened for us through the curtain, that is, his body… let us draw near to God with a sincere heart and with the full assurance that faith brings…”

Notice what Hebrews calls the curtain: His body. At the very moment Jesus gave up His life, the curtain in the temple was torn in two (Matthew 27:50-51). Through His body, given for us, the barrier between God and us came down.

The night before He died, Jesus had already given a name to what His death would bring: the new covenant. He took the cup and said:

Luke 22:20 (NIV) — “This cup is the new covenant in my blood, which is poured out for you.”

Under the old covenant, one man could enter God’s presence, once a year, with the blood of an animal. Under the new covenant, everyone who trusts in Jesus can draw near, any day, because of His blood. The way in has been open ever since.

Preaching to the Spirits in Prison

After His death, Jesus descended to Hades — the realm of the dead — and proclaimed His victory over sin and death.

1 Peter 3:18-20 (NIV) — “For Christ also suffered once for sins, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive in the Spirit. After being made alive, he went and made proclamation to the imprisoned spirits — to those who were disobedient long ago when God waited patiently in the days of Noah while the ark was being built.”

Christians have long differed over who these spirits were. The reading that fits the passage most naturally is that they were human beings — the generation that rejected God’s warnings in Noah’s day and perished in the flood. Notice how precisely Peter dates them. Not the disobedient in general, but those who were disobedient in the days of Noah.

So Jesus, after His death and before His resurrection, went to these souls and proclaimed His victory over sin and death.

Victory Over Death

By rising from the dead, Jesus conquered death itself, fulfilling the prophecy of

Psalm 16:10 (NASB) — “For You will not abandon my soul to Sheol; You will not allow Your Holy One to undergo decay.”

After His resurrection, Jesus declared

Revelation 1:18 (NIV) — “I am the Living One; I was dead, and now look, I am alive for ever and ever! And I hold the keys of death and Hades.”

His death did more than defeat death itself. It broke the hold of the one who had been using death as a weapon:

Hebrews 2:14-15 (NIV) — “he too shared in their humanity so that by his death he might break the power of him who holds the power of death — that is, the devil — and free those who all their lives were held in slavery by their fear of death.”

Colossians 2:14-15 (NIV) — “having canceled the charge of our legal indebtedness, which stood against us and condemned us; he has taken it away, nailing it to the cross. And having disarmed the powers and authorities, he made a public spectacle of them, triumphing over them by the cross.”

Notice how He did it. Not by avoiding death, but by walking into it. The weapon the enemy had held over humanity since Eden was taken out of his hand — by being used on Christ, and failing.

Giving Us the Gift of the Holy Spirit

John 16:7 (NIV) — “But very truly I tell you, it is for your good that I am going away. Unless I go away, the Advocate [the Holy Spirit] will not come to you; but if I go, I will send him to you.”

After Jesus’ ascension, the Holy Spirit was poured out on the day of Pentecost.

Acts 2:1-4 (NIV) — “When the day of Pentecost came, they were all together in one place. Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.”

This is one of the clearest reasons Jesus gave for His own departure. His going made a way for the Spirit to come — not to a tent or a temple, but into His people. And the Holy Spirit is not reserved for a select few. He is the gift for all believers.

Becoming Our High Priest

We have already seen what the old priests could not do. They were sinners themselves, and their work was never finished.

But how could Jesus be a priest at all? He came from the tribe of Judah, and the law only allowed priests from the tribe of Levi (Hebrews 7:14).

Long before, God had spoken of a different kind of priest, one like Melchizedek, the king of Salem and “priest of God Most High” who blessed Abraham (Genesis 14:18-19). A king and a priest at the same time, long before Levi was even born (Psalm 110:4).

Hebrews says Jesus is that priest:

Hebrews 7:16-17 (NIV) — “one who has become a priest not on the basis of a regulation as to his ancestry but on the basis of the power of an indestructible life. For it is declared: ‘You are a priest forever, in the order of Melchizedek.'”

Jesus is a different kind of priest altogether — and one detail is easy to miss. He is still working.

Hebrews 7:24-25 (NIV) — “But because Jesus lives forever, he has a permanent priesthood. Therefore he is able to save completely those who come to God through him, because he always lives to intercede for them.”

He never needed an offering for Himself, because He had no sin of His own to answer for.

Hebrews 7:27 (NIV) — “Unlike the other high priests, he does not need to offer sacrifices day after day, first for his own sins, and then for the sins of the people. He sacrificed for their sins once for all when he offered himself.”

Jesus’ sacrifice was so complete that He entered the heavenly Holy of Holies carrying His own blood.

Hebrews 9:12 (NIV) — “He did not enter by means of the blood of goats and calves; but he entered the Most Holy Place once for all by his own blood, thus obtaining eternal redemption.”

Through this act, Jesus fulfilled the Old Testament priesthood perfectly. His blood secured permanent forgiveness and direct access to God for all believers.

Why He Did It

We have looked at a great deal in this chapter — prophecy fulfilled, sacrifices ended, a curtain torn, death defeated, a High Priest who never dies.

But none of it explains the one thing that matters most. Why would He?

He was not forced. He said plainly, “No one takes it away from Me, but I lay it down on My own” (John 10:18). He could have called on twelve legions of angels (Matthew 26:53). He did neither.

Paul gives the reason in a single sentence:

Romans 5:8 (NIV) — “But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.”

Not after we cleaned ourselves up. Not once we had earned it. While we were still sinners.

That is why Jesus had to die. The law required a payment, and love volunteered to make it.
