First argument:

Eternal Power is essential to Divine Essence, for it is an indispensable attribute of Divinity. They are identical in one respect: Any incapacity is impossible, for this would presuppose the existence of two opposites in the Infinite Being. Since this is impossible, and since impotence cannot occur in the Divine Essence, nothing can interfere with Divine Power. Since impotence cannot be involved with Divine Power, it can have no degrees, for such degrees of a thing's existence come about only through the intervention of opposites. Degrees of temperature occur because of cold's intervention, and degrees of beauty exist because of ugliness' intervention. This is true of all qualities in the universe. Contingent things and beings contain opposites, for they do not exist essentially of themselves and no undiluted quality is essential to their existence. As the World of Contingencies contains degrees and graduations, it is subject to change and transformation.

Since Eternal Divine Power contains no degrees, it is equally easy for it to create or bring into existence particles or galaxies. Resurrecting humanity is as easy for it as reviving one person, and creating spring is as easy as creating a flower. If creation or resurrection were ascribed to causes, creating a flower would be as difficult as creating spring. But if there is only One Creator, creating everything is as easy as creating one thing.
