“17 If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.” In other words the way to know the blessings of Psalm one is to move in terms of them, to delight in God’s law, to obey God’s law, to put ourselves under God’s authority, then we can have the blessings, because the knowledge of God cannot be abstract, it is a living thing.”

— R. J. Rushdoony
