Who should I believe? You? I have no reason to.And He opened their understanding, that they might comprehend the Scriptures. (Luk 24:45 NKJ)
And believe.
Jesus, who said those words to his disciples, died ca. 33 A.D.
John, whom you previously quoted, wrote the Book of Revelation in 98 A.D., well after Jesus said those words. You have a contradiction on your hands.
