Exodus I dont think you understand how God confirmed it to Peter. By opening his understanding so he could believe.

Luke 24:13-16
13        Now behold, two of them were traveling that same day to a village called Emmaus, which was about seven miles from Jerusalem.
14        And they talked together of all these things which had happened.
15        So it was, while they conversed and reasoned, that Jesus Himself drew near and went with them.
16        But their eyes were restrained, so that they did not know Him.
(NKJ)

Luke 24:30-31
30        Now it came to pass, as He sat at the table with them, that He took bread, blessed and broke it, and gave it to them.
31        Then their eyes were opened and they knew Him; and He vanished from their sight.
(NKJ)
