With all due respect, you are just making this up.
The Bible tells us otherwise: Jesus did many other things as well. If every one of them were written down, I suppose that even the whole world would not have room for the books that would be written. John 21:25
I’m not making anything up. You are accusing the early followers of Jesus of “making things up” to produce the written Gospels. Of course, they could not remember everything Jesus ever did, nor did they have any idea what the pre-incarnate Son might have done, unless it was recorded in the OT.
