It stands at the centre of the gospel
Christian faith is not built only on Jesus' teaching or the moving example of his life. It rests on the news that Jesus died for sins, was buried, and then rose again. Paul gave this message first place when he reminded the Corinthian church of the gospel he had received and passed on (1 Corinthians 15:3-5).
The resurrection says that the cross was not the end of Jesus' story. The one who willingly gave himself for sinners was raised by God, and many people encountered him alive afterwards (1 Corinthians 15:5-8). That is why the first Christians spoke not merely of ideas, but of a risen Christ.
For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures:
It assures believers of forgiveness
Paul faced the issue plainly. If Christ had not risen, faith would be futile and people would still be in their sins (1 Corinthians 15:17). Jesus' death was not a tragic defeat that needed rescuing by a comforting story. His resurrection shows that God accepted his saving work.
Romans connects Jesus' death with our sins and his resurrection with our being made right with God (Romans 4:25). Christians may describe the details of salvation in different ways, but they agree on this: forgiveness rests on what Christ has done, not on trying hard enough to earn God's welcome.
And if Christ be not raised, your faith is vain; ye are yet in your sins.
It gives hope beyond death
Death is painful and real, and Scripture does not pretend otherwise. Yet Jesus' resurrection means death does not have the final word. Paul calls Christ the firstfruits, meaning the first part of a harvest that promises more to come. His rising points forward to the resurrection of those who belong to him (1 Corinthians 15:20-23).
This hope is not escape from the world or denial of grief. It is confidence that God can restore what death has broken. Peter describes it as a living hope, because it comes through the resurrection of Jesus Christ rather than through wishful thinking (1 Peter 1:3).
Blessed be the God and Father of our Lord Jesus Christ, which according to his abundant mercy hath begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead,
It changes life in the present
The resurrection is also for ordinary Tuesday mornings. Through baptism, believers picture being joined to Christ in his death and raised to live a new kind of life (Romans 6:4). Christians differ on the practice and timing of baptism, but this passage makes the central point clear: union with the risen Jesus shapes how a person lives now.
That doesn't mean Christians never fail or struggle. It means sin, despair, and death need not rule them as before. The risen Christ gives people reason to persevere, serve, forgive, and face suffering with hope. Read the resurrection accounts for yourself, especially the first witnesses at the empty tomb, and consider what it means that Jesus is alive (Luke 24:1-5).
