Which philosophical question does Plantinga address regarding God's power?

Plantinga's work primarily grapples with the nature of God’s omnipotence, particularly exploring the concept of whether God can limit His own power. This question delves into the idea of omnipotence and the logical consistency of what it means for an all-powerful being to possess or choose to constrain His omnipotence.

In philosophy, there are significant discussions around the implications of omnipotence, such as whether true omnipotence includes the capacity to do logically contradictory things. Plantinga argues that it is not a limitation of God's power if He chooses not to do something that is self-contradictory or logically impossible. By addressing whether God can limit His omnipotence, Plantinga posits that the nature of divine power is not merely about the ability to do all things indiscriminately, but also about the nature and consistency of those actions. Understanding this dimension helps clarify the philosophical inquiry into the essence of divine attributes.
