After the Sabbath, as the first day of the week was dawning, Mary Magdalene and the other Mary went to view the tomb. There was a violent earthquake, because an angel of the Lord descended from heaven and approached the tomb. He rolled back the stone and was sitting on it. His appearance was like lightning, and his clothing was as white as snow. The guards were so shaken by fear of him that they became like dead men.

The angel told the women, “Don’t be afraid, because I know you are looking for Jesus who was crucified. He is not here. For he has risen, just as he said. Come and see the place where he lay. Then go quickly and tell his disciples, ‘He has risen from the dead and indeed he is going ahead of you to Galilee; you will see him there.’ Listen, I have told you.”

So, departing quickly from the tomb with fear and great joy, they ran to tell his disciples the news. Just then Jesus met them and said, “Greetings!” They came up, took hold of his feet, and worshiped him. - Matthew 28:1-9

Now if Christ is proclaimed as raised from the dead, how can some of you say, “There is no resurrection of the dead”? If there is no resurrection of the dead, then not even Christ has been raised; and if Christ has not been raised, then our proclamation is in vain, and so is your faith. Moreover, we are found to be false witnesses about God, because we have testified wrongly about God that he raised up Christ—whom he did not raise up, if in fact 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 worthless; you are still in your sins. Those, then, who have fallen asleep in Christ have also perished. If we have put our hope in Christ for this life only, we should be pitied more than anyone.

But as it is, Christ has been raised from the dead, the firstfruits of those who have fallen asleep. For since death came through a man, the resurrection of the dead also comes through a man. For just as in Adam all die, so also in Christ all will be made alive. - 1 Corinthians 15:12-22
