By What System Does Hashem Orchestrate History?

"AND YOU INTENDED HARM AGAINST ME, BUT G-D INTENDED IT FOR GOOD." (Breishis 50:20)

From this model which the Torah supplies we must learn that all harm which men or nature inflict upon die innocent is really intended by G-d for good. But, in addition, we learn that Hashem purposefully conceals His Hand so that righteous men be tested to discern by their own efforts that whatever transpired was really the benevolent plan of Hashem. G-d made the world that it should "do" in a seemingly automatic manner of cause and effect, either in cycles or in random accident, in order to supply the virtuous with opportunity to discover the truth and thereby grow great. These links in the chain of cause and effect which blind m any from recognizing the hand of G-d, are the very best  and most  effective means of teaching the better men to see how G-d Himself is manipulating all events for His purpose. --The Beginning
