does that mean that the Bible is actually truthful and we should believe it all and act on everything it teaches?
That is another debate
If they are provided with spiritual food from Jesus to dispense how come they were not told who they are ?
If Jesus is the source of the food then how can the FDS "prepare" food imperfectly? But not knowing who they are is not a qualifying factor, "doing so" is. FDS is identified by Jesus finding them dispensing food when he comes -according to the verse.
