The four witnesses are like unto men standing by the way side doing word of mouth publicity. They will keep narrating the same things in myriad forms. For they cannot say their words as they did before but they would narrate facts as they happen to them.

So, the four writings of the gospel of Jesus Christ are like that. Each man wrote what he saw, as he remembered it. Not as it happened, but way later; so both time and chance played a serious role in their contradictions and agreements. But at the end of it all, they all say they saw Jesus and he walked among them. That is enough evidence to move us to follow him to the cross.

And when we reconcile the evidence brought about by the four books, they are all centered on the fact that he did work the miracles, and he did live among them, and he did teach a certain way and he said to them he is going ahead to prepare us a place.
