A few quotes from the Rabbi on 'Israel and the Nations'
in which he teaches that the Holy One, blessed be He, is beneficent to His creatures so that they defend peace in the world
He - it clearly being His will – seeks to be beneficent to His creatures, desires that the world endure, that it be reconciled and repaired; and therefore increases His mercy forever, by crowning kings among them and imparting them of His sovereignty and awe. He imparts wisdom to the wise and instils their heart with His spirit's wisdom, so that they defend peace in the world and maintain its order, and by their dignity and wisdom subjugate those who would revolt. As our Sages said, "Pray for the welfare of the government, for were it not for the fear of it, man would swallow his fellow alive."
