IDENTITY BETWEEN GOD'S WILL AND HIS WILLING
Hence it is also clear that the divine will is the very act of willing in God. As has been pointed out, God's will is identical with the good willed by Him. But this would be impossible if His willing were not the same as His will; for willing is in the will because of the object willed. Accordingly God's will is His willing.
Again, God's will is the same as His intellect and His essence. But God's intellect is His act of understanding, and His essence is His existing. Therefore His will must be His act of willing. And so we see clearly that God's will is not opposed to His simplicity.
