What does Luke 24:14 mean?

Two men, disciples of Jesus, finally have the chance to leave Jerusalem. They had come for the Passover and stayed when the Romans crucified Jesus thanks to the Jewish Sanhedrin's manipulations. The men, as well as several other disciples, hid in a locked room for fear of the Jewish leaders. Now that the Sabbath is over and the sun has risen, they can leave (Luke 24:13; John 20:19).

As they travel, they discuss what they've witnessed. They thought Jesus was the Messiah who was going to save Israel from the Romans—bring back God's favor to His chosen people. To watch Him hang from a cross was both confusing and horrific. His power to heal and His wise words were proof that He had come from God. How could He be destroyed by the leaders of the people He'd come to save (Luke 24:19–20)?

But then, that morning, the women disciples went to the tomb and found it empty. Where's His body? Who stole it? What did the women mean when they claimed angels appeared and told them that Jesus had risen from the dead? And then Peter and John went to the tomb and found it empty, as well (Luke 24:21–24; John 20:1–10).

The two men can't make sense of it. Jesus raised people from the dead, but He was crucified. How could He come back to life?
