[God's decrees were] formed within Himself. He needed not to go without Himself, either for the impulse which led to it, or the knowledge in which it was conceived. He had all knowledge, both of the actual and the possible, all wisdom as to the best end and means, all power to execute what He devised in the use, or without the use of appropriate secondary means, and free will to select, of all possible plans and means, whatever He Himself should please, and the impulse which moved Him existed alone in that knowledge and will.
James Boyce
