They thought that he was a ghost! So would I have done! And being forever perceptive he asks them why they are troubled! And some of them obviously thought-this cant be ~jesus. So he asked them to touch him. You cant touch a ghost! Look at my hands and my feet. It is me myself! Touch me and see; a ghost does not have flesh and bones, as you see I have.”
When he had said this, he showed them his hands and feet. And some of them still did not believe it because of joy and amazement, So we have a ghost with a gaping hole that you can feel. Or maybe it's just a story, a comfortable way of resolving grief, collective transference. So to answer their doubts he asked them, “Do you have anything here to eat?” They gave him a piece of broiled fish, and he took it and ate it in their presence.

He opened their minds so they could understand the Scriptures. He told them, “This is what is written: The Christ will suffer and rise from the dead on the third day, and repentance and forgiveness of sins will be preached in his name to all nations(ethnos), beginning at Jerusalem. You are witnesses (marturio) of these things.
Have you ever doubted the existence of God? Many of at times have doubted. But our experience of God turns doubt into faith. God comes to us at strange times and jolts us from doubt to faith. We will not have the experience that the disciples had of feeling the holes where Jesus was pierced but something else cuts through and we believe.
There are a number of resurrection stories. Jesus convinced the disciples he was alive, through convincing proofs, for 40 days after the resurrection.
Ultimately It is only God who can convince us that God is with us even though we do cannot feel the marks of the crucified body of Jesus, although maybe we have our own scars, our own crucifixions. Unlike ourselves God never loses faith in us, never doubts us. There will be deaths and there will be resurrection because it’s the rhythm of the universe.
