This story cannot be found in the scriptures, but it is told that after his resurrection, Jesus appeared to an old fisherman.
"I am Jesus and I have returned to show God's love and power."
"No, you're not Jesus. Go away! You're scaring all the fish," answered the old fisherman.
"I see you are full of doubt. What would you have me do to show who I am?"
"Walk across the river," the old fisherman tells Jesus.
Jesus starts walking across the river, but he sinks and disappears under the water. After he swims back to shore, the old fisherman says to him, "See, you're not Jesus. You can't walk on water!"
Jesus responds, "Well, I used to be able to do it, but then I got these holes in my feet!"
