 Also, the prophecy goes on. He says, I will show wonders in the heaven above and signs in the earth beneath, blood and fire, vapor of smoke. The sun shall be turned into darkness and the moon into blood before that great and notable day of the Lord come. Now, I don't know what Peter made of that exactly because he doesn't go on to explain. But the heavenly signs of the sun and moon being turned into blood or darkness are not there.
