How was Avraham Avinu able to unite an entire world of committed pagans to accept the monotheistic belief? A world filled with idol worshippers, each devoted to a form of sheker, falsehood, left their idols and joined the ranks of believers. How did this occur? He showed them the truth. Someone who is living the life of a lie will eschew the lie as soon as the truth glares at him. Avraham taught the world the meaning of emes, truth. When they saw the truth, they realized the falsehood to which they had been adhering. Our Patriarch could have easily shied away from reaching out to these people. “They are different. Why bother?” Avraham understood that when a person is presented with the truth in its pristine and unembellished form, he simply must listen. Horav Yitzchak Kirzner, zl, observes that there are 20 words in the brachah of Teka b’Shofar, coinciding with the 20 generations that preceded Avraham Avinu. This is to say that in the merit of our Patriarch, we will again be unified as one people. Diverse groups could ultimately come together as one, when the light of the truth illuminates their minds. From the allusion to Avraham, we see that (while it might appear impossible), when shown the truth, an entire world can be united under the banner of Hashem. During the ingathering of the exiles (both physical and spiritual), all Jews will be united in their belief in Hashem.
