What is the definition of the work of creation?

The work of creation refers specifically to God's act of bringing into existence everything that exists, particularly emphasizing the concept of creation ex nihilo, which means "out of nothing." The correct choice encapsulates this idea by stating that God made all things by His power, highlighting both His omnipotence and the nature of creation itself. This aligns with the theological understanding that God is the ultimate source of all that is, having created the universe and everything within it without using pre-existing materials.

In contrast, the other choices focus on different aspects of existence or processes. Acknowledging the existing universe does not convey the act of creation itself but rather a recognition of what has already been made. Restoring the world after its fall pertains to redemption and restoration rather than the initial act of creation. Observing natural processes over time is related to understanding the world through science and does not address the divine initiative behind creation. Thus, option B is the definition that most accurately reflects the theological perspective on the work of creation.
