ok heres another thing that always worried and puzzled me... Moses made great sacrifices to lead the Isrealites and endured great hardship to do so... but he makes one mistake and suddenly all that counts for nothing and he gets no rewards for his pains at all!????!
this has never seemed fair to me. Basicly what is seems to be saying is that you can lead a exemplary life at great cost to your self, but if you make one mistake... thats it youv'e blown it!
