Avraham and Noach are both called Tzadikim yet in some aspect Avraham’s perfection was considered on a much higher level. How can we understand in practical terms for us in this generation that there are different levels of righteousness that can be attained?Let us use an analogy that will shed light on this holy matter. Picture someone that is suffering from a headache, runny nose and cough all at the same time. One level of doctor will give him aspirin for the headache, an antihistamine for the runny nose and cough syrup for the congestion. Within a short period of time the sick person will feel relief from all three discomforts, however tomorrow all these symptoms will probable reoccur. A more educated doctor will besides possibly these immediate remedies for temporary relief will also give him an antibiotic to take for a number of days in order to uproot the internal infection that is causing this uncomfortable symptoms. A even more educated doctor besides prescribing all of the above will also offer suggestions to help avoid the problem in the future such as increased regular intake of vitamin C and other nutritional supplements, improving the diet, working on personal stress management. There were some other tzadkim besides Avraham and Noach who were on the first level of advising other on how to relief their immediate “uncomfortable symptoms” by taking spiritual aspirin etc.. Then there was Noach who also advised others on how to temporarily uproot the “illness” by taking spiritual antibiotics. And then there was Avraham Avinu who would also give advice to the spiritually ill on how to permanently uproot any potential spiritual “illness” from overwhelming them. This then helps us understand and appreciate the great difference between Avraham’s level of perfection and Noach’s.
