Philip Schaff

“ For if it had arisen contrary to His determination, or from some other substance or cause, then God would not have had firmness of will: for perchance, even though He should not wish it, leaders of evil might continually arise, who would war against His wishes. But it is impossible that this should be the case. For no living being, and especially one capable of giving guidance, can arise from accident: for everything that is produced must be produced by some one. ”
