  Inasmuch as it is known that God, may He be blessed, is the sources and fountain of all perfection, and in virtue of his perfection, which is His essence, He loves the good, as may be seen from His actions in bringing into existence the entire universe, sustaining it perpetually, and continuously creating it anew, and all be means of His simple will, it must necessarily be that the love of the good is an essential property of perfection. It follows from this that the greater perfection [of the lover] the greater will be the love and the pleasure in the  desire.[48]
