Avb - and while reading further in John 2:24-25 it says that Jesus would not entrust himself to them, for he knew all men. He did not need man's testimony about man, for he knew what was in a man.
Jesus himself said it...he did not trust man. Just think, all the years that we as JW's believed the GB (mere men) and what they said. All the Watchtowers and the different rules that were written and we followed everything and believed men.
