Quote from Baal HaSulam:
And he reasons all that “the earth shall be full of the knowledge of the Lord, as the waters cover the sea (Isaiah 11, 9)”. Thus we see that the prophet conditions peace in the whole world with the filling of the whole world with the knowledge of God, just as we have said that the tough, egoistic resistance between people, along with deterioration in the international relationships, all these will not cease from the world by any human counsel under any conditions.

Our eyes can see how the poor sick turn over in dreadful pain, and humanity has already thrown itself to the extreme right as with Germany or to the extreme left, as with Russia, and not only did they not ease the pain, they have worsened the malady and agony and the voices rise up to the sky as we all know.

Therefore they have no counsel but to come to the acceptance of His burden, meaning that they aim their acts to the will of the Lord and to His purpose, as He had planned prior to creation. And when they do that, it is plain to see that with His work all envy and hatred will be abolished from mankind as I have shown above thus far, because then all members of humanity will unite into one body with one heart full of the knowledge of the Lord. Thus, world peace and the knowledge of God are one and the same thing.

Baal HaSulam, “The Peace.”
