Rav S. R.Hirsch - we can't emulate great men who are portrayed as flawless

Rav S. R. Hirsch(Bereishis 12: 10 – 13):.  The Torah does not seek to portray our great men  as perfectly ideal figures; it deifies no man. It says of no one: “Here you  have the ideal; in this man the Divine assumes human form!” It does  not set before us the life of any one person as the model from which  we might learn what is good and right, what we must do and what we  must refrain from doing. When the Torah wishes to put before us a  model to emulate, it does not present a man, who is born of dust.  Rather, God presents Himself as the model, saying: “Look upon Me!  Emulate Me! Walk in My ways!” We are never to say: “This must be  good and right, because so-and-so did it.” The Torah is not an “anthology  of good deeds.” It relates events not because they are necessarily  worthy of emulation, but because they took place.    The Torah does not hide from us the faults, errors, and weaknesses  of our great men, and this is precisely what gives its stories credibility.  The knowledge given us of their faults and weaknesses does not detract  from the stature of our great men; on the contrary, it adds to their  stature and makes their life stories even more instructive. Had they  been portrayed to us as shining models of perfection, flawless and  unblemished, we would have assumed that they had been endowed  with a higher nature, not given to us to attain. Had they been portrayed  free of passions and inner conflicts, their virtues would have seemed  to us as merely the consequence of their loftier nature, not acquired  by personal merit, and certainly no model we could ever hope to  emulate.
