Lesson 2 of 5 — Knowing Christ: A Study

Why Did Jesus Die and Rise for Us?

Purpose of this lesson: To see from Scripture why the cross was necessary, what Jesus accomplished through His death, and why His resurrection is central to the Christian hope and to the new life we are called to live in Him.

Jesus died to deal with sin and rose so that we may receive forgiveness, reconciliation, and new life in Him.

Studying with someone? Read the Scriptures aloud together, move slowly, and leave room for honest questions. The goal is not to rush through material, but to see Christ clearly and respond to Him sincerely.

1. Sin Brought Death, and the Sacrifices Pointed to Christ

In the beginning, God created humanity for life with Him.

Human beings were not created for sin, corruption, separation from God, or death. They were created to know God, live in His presence, and share in His goodness.

But through Adam's disobedience, sin entered the human story, and death came through sin. Paul wrote:

"Through one man sin entered into the world, and death through sin..."
Romans 5:12
"All have sinned..."
Romans 3:23

Sin is not only weakness or imperfection. At its root, sin is a turning away from God — from His authority, His goodness, and His life. Because God is holy, sin cannot be treated as harmless.

"God is Light, and in Him there is no darkness at all."
1 John 1:5
"The wages of sin is death..."
Romans 6:23
Main idea Sin is a turning away from God. Because God is holy, sin brings guilt, separation from God, and death. This raises the central question: How can sinners be forgiven and brought back to God without God ignoring sin or denying His holiness?

Under the Mosaic Law, God taught Israel that sin requires atonement. Sin brings death, so a life had to be given.

"The life of the flesh is in the blood... it is the blood by reason of the life that makes atonement."
Leviticus 17:11
"Without the shedding of blood there is no forgiveness."
Hebrews 9:22

This does not mean God enjoys death. It means sin is serious. Forgiveness is not God pretending sin does not matter. Forgiveness means God deals with sin truthfully, righteously, and mercifully.

The sacrifices under the Law prepared God's people to understand this. But those sacrifices were not the final answer.

"The Law... has only a shadow of the good things to come..."
Hebrews 10:1
"It is impossible for the blood of bulls and goats to take away sins."
Hebrews 10:4

The sacrifices were shadows. Christ is the reality.

John the Baptist pointed to Jesus and said:

"Behold, the Lamb of God who takes away the sin of the world!"
John 1:29

Isaiah had spoken beforehand about the suffering Servant:

"He was pierced for our offenses..."
Isaiah 53:5
"The LORD has caused the wrongdoing of us all to fall on Him."
Isaiah 53:6

Jesus fulfilled what the sacrifices pointed to. He did not offer another temporary sacrifice. He offered Himself once for all.

"We have been sanctified through the offering of the body of Jesus Christ once for all time."
Hebrews 10:10

God also gave another picture in the wilderness. When Israel sinned and many were dying, God told Moses to lift up the bronze serpent, so that those who looked would live.

"Everyone who is bitten, when he looks at it, will live."
Numbers 21:8

Jesus later said this pointed to Him:

"As Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up..."
John 3:14

Just as the dying Israelites were given life by looking in faith, so humanity under sin and death is given salvation through Christ lifted up on the cross. The provision comes from God. It must be received by faith.

This is why Paul summarized the Gospel this way:

"Christ died for our sins... He was raised on the third day..."
1 Corinthians 15:3–4

2. Jesus Died Once for All to Bring Us Back to God

The cross begins with the love of God.

"God so loved the world..."
John 3:16
"While we were still sinners, Christ died for us."
Romans 5:8

Jesus did not die for people who had already made themselves worthy. He died for sinners.

But the cross is more than a general act of mercy. Jesus bore our sins and carried what we could not carry.

"He Himself bore our sins in His body on the cross..."
1 Peter 2:24
"Christ also suffered for sins once for all time, the just for the unjust, so that He might bring us to God."
1 Peter 3:18
Main idea This is the heart of the cross. The just One suffered for the unjust. The sinless One gave Himself for sinners. The purpose was not only that we would escape punishment, but that we would be brought back to God.

Jesus gave His life willingly.

"I lay down My life..."
John 10:17
"The Son of Man did not come to be served, but to serve, and to give His life as a ransom for many."
Mark 10:45

At the cross, God does not ignore sin — and He does not abandon sinners. Sin is judged. Mercy is given. God remains holy. And sinners are forgiven.

"Just and the justifier of the one who has faith in Jesus."
Romans 3:26
"God was in Christ reconciling the world to Himself..."
2 Corinthians 5:19

Reconciliation means that a broken relationship is restored. Because of sin, humanity became distant from God. But through Christ, God opens the way back to Himself.

This was shown when Jesus died:

"The veil of the temple was torn in two from top to bottom."
Matthew 27:51

Under the old covenant, the high priest entered the Most Holy Place only once a year. But through Jesus, the way into God's presence has been opened for all who come to Him.

"We have confidence to enter the holy place by the blood of Jesus..."
Hebrews 10:19
"Approach God with a sincere heart in full assurance of faith."
Hebrews 10:22

We do not come carelessly. But we do come with confidence, reverence, and faith.

"I am the way, and the truth, and the life; no one comes to the Father except through Me."
John 14:6

Through Him we receive peace with God and are brought into God's family.

"Having been justified by faith, we have peace with God through our Lord Jesus Christ."
Romans 5:1
"To them He gave the right to become children of God."
John 1:12
"You have received a spirit of adoption..."
Romans 8:15
Jesus died so that sinners may be forgiven, cleansed, reconciled to God, brought near, and received as children of God.

3. Jesus Rose So We Could Receive New Life in Him

Jesus did not remain in the grave.

If Jesus had died and stayed dead, the Christian message would be empty.

"If Christ has not been raised, your faith is worthless..."
1 Corinthians 15:17

But Christ has been raised.

"God raised Him up again..."
Acts 2:24

Death could not hold Him. The Father vindicated Him. His sacrifice was accepted. Death was conquered. Jesus is the living Lord.

"Declared the Son of God with power by the resurrection from the dead..."
Romans 1:4
"A living hope through the resurrection of Jesus Christ from the dead."
1 Peter 1:3

The resurrection means that forgiveness is real. Reconciliation is real. Eternal life is real. And new life is possible.

"We too might walk in newness of life."
Romans 6:4

The Gospel is not only that Jesus died so we may be forgiven. It is also that Jesus rose so we may live a new life in Him. Christ saves us not only from the guilt of sin, but also from the power of sin.

"Our old self was crucified with Him..."
Romans 6:6
"All of us who have been baptized into Christ Jesus have been baptized into His death... we have been buried with Him through baptism into death..."
Romans 6:3–4

Christ died, and we are called to die to sin. Christ was buried, and we are called to leave the old life behind. Christ rose, and we are called to walk in newness of life.

"If we have become united with Him in the likeness of His death, certainly we shall also be in the likeness of His resurrection."
Romans 6:5
"Consider yourselves to be dead to sin, but alive to God in Christ Jesus."
Romans 6:11

Grace does not make sin harmless. Grace forgives sin and frees us from its rule.

"Are we to continue in sin so that grace may increase? Far from it!"
Romans 6:1–2

The right response to Jesus' death and resurrection is repentance and faith.

"Repent and believe in the gospel."
Mark 1:15
"If you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved."
Romans 10:9

Repentance means turning back to God. Faith means trusting Christ. We stop defending our sin. We stop trusting ourselves. We come to Christ for mercy, forgiveness, reconciliation, and life.

"Come to Me, all who are weary and burdened, and I will give you rest."
Matthew 11:28
"Worthy is the Lamb..."
Revelation 5:12
"To Him who sits on the throne, and to the Lamb be blessing and honor and glory and dominion forever and ever."
Revelation 5:13
Main idea The cross and resurrection lead us to repentance, faith, worship, and new life. Because Christ rose, we too are called to walk in newness of life — dead to sin, alive to God.

Key Truth

God created humanity for life with Him.

Through Adam, sin and death entered the human story, and every person also sins personally.

Because sin brings death, sin had to be dealt with.

The animal sacrifices under the Mosaic Law showed that forgiveness requires atonement, but they were only shadows pointing to Christ.

Jesus died for our sins once for all. He bore our sins, carried what we could not carry, and opened the way back to God.

Jesus rose again so that those who belong to Him may receive eternal life, become children of God, and walk in newness of life.

"Christ died for our sins... He was raised on the third day..."
— 1 Corinthians 15:3–4

"I am the way, and the truth, and the life; no one comes to the Father except through Me."
— John 14:6

Check Your Understanding

  1. Multiple choice: According to Romans 6:23, what is the result of sin?

    • A. A life of difficulty and suffering
    • B. Separation from one's family
    • C. Death — but the free gift of God is eternal life in Christ Jesus
    • D. A second chance to live better
    Show suggested answer

    C. Romans 6:23 says "the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord." Sin leads to death — separation from God — but God's grace offers eternal life through Jesus.

  2. True or false: Jesus died by accident, as a victim of human injustice, rather than as part of God's plan.

    Show suggested answer

    False. While human sin and injustice were involved, the Scriptures teach that Jesus's death was God's plan from before creation. Isaiah 53 describes the suffering servant whose wounds bring healing. Acts 2:23 says Jesus was "delivered up according to the definite plan and foreknowledge of God." The cross was not a tragedy but a sacrifice.

  3. Scripture connection: 1 Corinthians 15:3–4 says Christ "died for our sins in accordance with the Scriptures, was buried, and was raised on the third day in accordance with the Scriptures." Why does Paul emphasise "in accordance with the Scriptures" twice?

    Show suggested answer

    Paul emphasises this to show that the death and resurrection of Jesus were not unexpected events. They fulfilled what God had promised through the prophets. Jesus is the one the whole of Scripture pointed toward. His death and resurrection confirm that God's word is true and His plan has been accomplished.

  4. In your own words: What does the resurrection of Jesus mean — not just as a historical event, but for those who trust in Him?

    Show suggested answer

    The resurrection means death has been defeated. Jesus did not stay dead, which confirms that He has power over death and that sin's final consequence has been overcome. For those who trust in Him, the resurrection is the ground of hope — that death is not the end, and that the life Jesus gives is eternal.

  5. Personal response: Romans 5:8 says "God shows his love for us in that while we were still sinners, Christ died for us." What does it mean to you that Christ died not after you became worthy, but while you were still a sinner?

    Show suggested answer

    There is no single correct answer. This question invites honest reflection on grace: that God's love was not withheld until we earned it. The cross shows that God moved toward us before we turned toward Him. This is grace — undeserved, freely given.
