This Generation, to Morrow, a Mat Is the Ten Minute Bible Hour

In the parable, jesus picks something from the natural world an i look at the signs. The signs tell you that the awaited thing is just around the corner. And further, i don't think these things is referring to the return of the son of man. But that these things only refer to the signs that point to it, not the actual event. That would seem to be what jesus is saying with all kinds of authority.
