Matthew 27:62-66 The next day, the one after Preparation Day, the chief priests and the Pharisees went to Pilate. “Sir,” they said, “we remember that while he was still alive that deceiver said, ‘After three days I will rise again.’ So give the order for the tomb to be made secure until the third day. Otherwise, his disciples may come and steal the body and tell the people that he has been raised from the dead. This last deception will be worse than the first.”
“Take a guard,” Pilate answered. “Go, make the tomb as secure as you know how.” So they went and made the tomb secure by putting a seal on the stone and posting the guard.
Did Jesus' disciples steal Jesus' body while Roman soldiers were guarding the tomb? This would have been impossible considering the soldiers own lives were in danger if the body went missing!
Matthew 28:1-7 After the Sabbath, at dawn on the first day of the week, Mary Magdalene and the other Mary went to look at the tomb.
There was a violent earthquake, for an angel of the Lord came down from heaven and, going to the tomb, rolled back the stone and sat on it. His appearance was like lightning, and his clothes were white as snow. The guards were so afraid of him that they shook and became like dead men.
The angel said to the women, “Do not be afraid, for I know that you are looking for Jesus, who was crucified. He is not here; 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 is going ahead of you into Galilee. There you will see him.’ Now I have told you.”
1 Corinthians 15:3-8 For what I received I passed on to you as of first importance: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures, and that he appeared to Peter, and then to the Twelve. After that, he appeared to more than five hundred of the brothers and sisters at the same time, most of whom are still living, though some have fallen asleep. Then he appeared to James, then to all the apostles, and last of all he appeared to me also, as to one abnormally born.
500 people all saw Jesus at the same time! How many witnesses does it take to prove an event happened? Like Ryley said, If Jesus wasn't resurrected then how come so many of these witnesses were willing to die terrible deaths for Jesus name?
The only logical explanation for the empty tomb is that Jesus was resurrected and is alive! He is risen!
Take the time to read 1 Corinthians 15:1-58.
