What is the fundamental duty required of man by God?

The fundamental duty required of man by God is obedience to God's revealed will. This principle is rooted in the belief that God has communicated His desires and expectations for humanity through Scripture and divine revelation. Obedience to God's will encompasses all aspects of life, directing individuals to align their actions, thoughts, and intentions with God’s commands and teachings.

This duty is foundational to the relationship between humanity and God, as it emphasizes living in accordance with His purposes rather than prioritizing personal enlightenment, community traditions, or merely participating in worship gatherings. While those elements can be important in a person's spiritual life, they are usually expressions or outcomes of a deeper commitment to obeying God's will. Ultimately, obedience signifies a response to God’s authority and an acknowledgment of His sovereignty, which is the core of what He requires from mankind.
