"And when he was come home he took a sword, and divided the dead body of his wife with her bones into twelve parts, and sent the pieces into all the borders of Israel. And when every one had seen this, they all cried out: There was never such a thing done in Israel from the day that our fathers came up out of Egypt, until this day: give sentence, and decree in common what ought to be done." Judges 19:29-30
"And some that were burying a man, saw the rovers, and cast the body into the sepulchre of Eliseus. And when it had touched the bones of Eliseus, the man came to life, and stood upon his feet." 4 Kings 13:21
My reaction on seeing the photo was sadness that they were in such poor condition. Also read elsewhere that the bones were found outside the box. Also another site I'm not familiar with said there were a few more bones, an ulna, tooth, piece of er cranium, and that they all tested as belonging to the same man.
Doesn't prove they belonged to John the Baptist but doesn't prove they don't. The pastor suggested they could be a harbinger of the soon coming of Christ just as John the Baptist was a harbinger of the man Jesus Christ who was about to embark upon his mission.
I guess I like to believe something is true then give it some time. Often I find I've been wrong but if serious red flags don't go up, try to keep an open mind. With God all things are possible.
