In the twenty-eighth chapter of the Gospel of Matthew, we read: "Now after the Sabbath, toward the dawn of the first day of the week, Mary Magdalene and the other Mary went to see the tomb. And behold, there was a great earthquake, for an angel of the Lord descended from heaven and came and rolled back the stone and sat on it. His appearance was like lightning, and his clothing white as snow. And for fear of him the guards trembled and became like dead men. But the angel said to the women, 'Do not be afraid, for I know that you seek Jesus who was crucified. He is not here, for
he has risen, as he said. Come, see the place where he lay. Then go quickly and tell his disciples that
he has risen from the dead, and behold, he is going before you to Galilee; there you will see him. See, I have told you.'" (Matthew 28:1-7, ESV)
Likewise, in the Gospel of Mark, we read: "When the Sabbath was past, Mary Magdalene, Mary the mother of James, and Salome bought spices, so that they might go and anoint him. And very early on the first day of the week, when the sun had risen, they went to the tomb. And they were saying to one another, 'Who will roll away the stone for us from the entrance of the tomb?' And looking up, they saw that the stone had been rolled back—it was very large. And entering the tomb, they saw a young man sitting on the right side, dressed in a white robe, and they were alarmed. And he said to them, 'Do not be alarmed. You seek Jesus of Nazareth, who was crucified. He has risen; he is not here. See the place where they laid him. But go, tell his disciples and Peter that he is going before you to Galilee. There you will see him, just as he told you.'" (Mark 16:1-7, ESV)
In the Gospel of Luke, we read: "But on the first day of the week, at early dawn, they went to the tomb, taking the spices they had prepared. And they found the stone rolled away from the tomb, but when they went in they did not find the body of the Lord Jesus. While they were perplexed about this, behold, two men stood by them in dazzling apparel. And as they were frightened and bowed their faces to the ground, the men said to them, 'Why do you seek the living among the dead? He is not here, but has risen. Remember how he told you, while he was still in Galilee, that the Son of Man must be delivered into the hands of sinful men and be crucified and on the third day rise.' And they remembered his words, and returning from the tomb they told all these things to the eleven and to all the rest." (Luke 24:1-9, ESV)
And, finally, in the Gospel of John, we read: "Now on the first day of the week Mary Magdalene came to the tomb early, while it was still dark, and saw that the stone had been taken away from the tomb. So she ran and went to Simon Peter and the other disciple, the one whom Jesus loved, and said to them, 'They have taken the Lord out of the tomb, and we do not know where they have laid him.' So Peter went out with the other disciple, and they were going toward the tomb. Both of them were running together, but the other disciple outran Peter and reached the tomb first. And stooping to look in, he saw the linen cloths lying there, but he did not go in. Then Simon Peter came, following him, and went into the tomb. He saw the linen cloths lying there, and the face cloth, which had been on Jesus' head, not lying with the linen cloths but folded up in a place by itself. Then the other disciple, who had reached the tomb first, also went in, and he saw and believed; for as yet they did not understand the Scripture, that he must rise from the dead. Then the disciples went back to their homes." (John 20:1-10, ESV)
Now, admittedly, there are variations in these accounts of Christ's resurrection. However, they all agree that the tomb was empty when his disciples arrived - that Jesus of Nazareth had risen from the dead. Interestingly, while only two of the Gospels supply a narrative about Christ's birth, all four of the canonical gospels contain an account of his death and resurrection! Hence, we are forced to conclude that this is an integral component/article of the Christian message/faith. Moreover, it isn't just the Gospel accounts which make this clear - the other writings of the New Testament reinforce the importance of this event!
In Peter's first sermon on the Pentecost following Christ's ascension to heaven, we read that he told the crowd: "Men of Israel, hear these words: Jesus of Nazareth, a man attested to you by God with mighty works and wonders and signs that God did through him in your midst, as you yourselves know— this Jesus, delivered up according to the definite plan and foreknowledge of God, you crucified and killed by the hands of lawless men. God raised him up, loosing the pangs of death, because it was not possible for him to be held by it. For David says concerning him, 'I saw the Lord always before me, for he is at my right hand that I may not be shaken; therefore my heart was glad, and my tongue rejoiced; my flesh also will dwell in hope. For you will not abandon my soul to Hades, or let your Holy One see corruption. You have made known to me the paths of life; you will make me full of gladness with your presence.’ Brothers, I may say to you with confidence about the patriarch David that he both died and was buried, and his tomb is with us to this day. Being therefore a prophet, and knowing that God had sworn with an oath to him that he would set one of his descendants on his throne, he foresaw and spoke about the resurrection of the Christ, that he was not abandoned to Hades, nor did his flesh see corruption. This Jesus God raised up, and of that we all are witnesses." (Acts 2:22-32, ESV) Once again, for Peter to have devoted so much of his message to the subject of Christ's resurrection, we are forced to conclude that this event was important/critical!
Likewise, in his epistle to the saints at Rome, Paul wrote: "For if while we were enemies we were reconciled to God by the death of his Son, much more, now that we are reconciled, shall we be saved by his life." (Romans 5:10) He asked "Who shall bring any charge against God's elect?" and "Who is to condemn?" He answered: "Christ Jesus is the one who died—more than that, who was raised—who is at the right hand of God, who indeed is interceding for us." (Romans 8:34) Paul also underscored the importance of Christ's resurrection for the saints at Corinth. He wrote: "For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures." (I Corinthians 15:3-4, ESV) Apparently, some folks were saying that there wasn't any such thing as a resurrection. Once again, Paul underscored the essential nature of Christ's resurrection to their faith. He wrote: "Now if Christ is proclaimed as raised from the dead, how can some of you say that there is no resurrection of the dead? But if there is no resurrection of the dead, then not even Christ has been raised. And if Christ has not been raised, then our preaching is in vain and your faith is in vain. We are even found to be misrepresenting God, because we testified about God that he raised Christ, whom he did not raise if it is true that the dead are not raised. For if the dead are not raised, not even Christ has been raised. And if Christ has not been raised, your faith is futile and you are still in your sins. Then those also who have fallen asleep in Christ have perished. If in Christ we have hope in this life only, we are of all people most to be pitied. But in fact Christ has been raised from the dead, the firstfruits of those who have fallen asleep. For as by a man came death, by a man has come also the resurrection of the dead. For as in Adam all die, so also in Christ shall all be made alive." (I Corinthians 15:12-22, ESV)
Indeed, we read in the book of Acts that ALL of the apostles preached about Christ's resurrection (Acts 4:33). Once again, Paul stressed the connection between Christ's resurrection to his own hope of being resurrected one day. He wrote to the saints at Philippi about his former life as a devout Jew: "whatever gain I had, I counted as loss for the sake of Christ. Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith— that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, that by any means possible I may attain the resurrection from the dead." (Philippians 3:7-11, ESV) Likewise, in the first epistle of Peter, we read: "Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you." (I Peter 1:3-4, ESV)
Hence, it is cleat that Christ's victory over death makes our own resurrection possible someday! Yes, we celebrate Christ's death every time we partake of the Eucharist/Lord's Supper/Passover, but we celebrate Christ's resurrection every day of our brief lives on this planet! After all, the fact of his resurrection makes eternity accessible to those of us who believe that it happened!
