2 Peter 1:16-18 (ESV)
For we did not follow cleverly devised myths when we made known to you the power and coming of our Lord Jesus Christ, but we were eyewitnesses of his majesty.  For when he received honor and glory from God the Father, and the voice was borne to him by the Majestic Glory, "This is my beloved Son, with whom I am well pleased,"  we ourselves heard this very voice borne from heaven, for we were with him on the holy mountain.
“We did not follow cleverly devised myths.” Already the charge is being leveled, “this is just mythical mumbo jumbo. No one ever rises from the dead.” Well that is the thought. And today people try to find parallels in Greek myths, and other mythical traditions. Yet scholarship is more and more leaning in the direction that these myths were being altered to mimic the story of Christ’s resurrection rather than the other way around. The charge is leveled and Peter answers it. Of course if you don’t believe him you don’t believe him. But notice he is saying we.
Peter isn’t relying solely on his own witness, but we. If it was just him one might say it was an hallucination. But he says we, and other people do not participate in another’s hallucination. They saw Jesus together, and this is not a cleverly devised myth. They don’t present it as such, and don’t expect it to be believed as such. They don’t mean to be giving you one of those really awful Easter sermons that talk about Jesus living in your heart. He only lives in your heart if he actually lives.
And the story isn’t all that clever, but it is true. It is reliable. Jesus lives, He is risen.
