Which term describes the nature of God being unchanging?

The term that describes the nature of God being unchanging is "immutable." This concept highlights the theological principle that God does not change in His nature, purposes, or promises over time. In Christian theology, immutability emphasizes God's perfection, suggesting that he is fully consistent and dependable. This means that His character and His will remain constant, providing believers with a foundation of trust in His eternal nature and faithfulness.

In contrast, the other terms convey different meanings. "Finite" indicates limitations, which contradicts the idea of an all-powerful, eternal God. "Dynamic" suggests changeability or the ability to evolve, which stands in opposition to the concept of God's unchanging nature. "Dualistic" refers to a belief system that posits two opposing forces, often seen in contexts like good versus evil, and does not pertain to the nature of God's immutability. Thus, "immutable" is the appropriate term to describe God’s unchanging nature within the theological framework.
