"The next day John saw Jesus coming toward him, and said, 'Behold! The Lamb of God who takes away the sin of the world! '" (John 1:29)
That was not a prophecy. And that language is not accommodating in any way ala Ping’s theory. What you have is a perfectly descriptive statement of Christ’s purpose in coming into the world.
If you are content to confuse that sort of statement made by John with the highly suspect and unscriptural notion that when God said "horses" in the Bible He really meant F-16s, you are on your own.
That is highly suspect. Those would have to be winged horses to be F-16s.
