Final answer:
Natural revelation alone is insufficient to fully know God because it is limited by our human intellect and sensory perception. It does not provide a comprehensive understanding of God's characteristics and his plan for humanity.
Step-by-step explanation:
Natural revelation, which refers to the knowledge of God gained through observing the natural world, is insufficient for us to know God fully. While natural revelation can provide us with some understanding of God's existence and attributes, it has limitations in comprehending the fullness of God.
One reason natural revelation alone is insufficient is because our understanding of God is limited by our human intellect and sensory perception. We can observe the effects of God's creation in the natural world, but we cannot fully grasp or comprehend the essence of God.
Furthermore, natural revelation does not provide a comprehensive understanding of God's characteristics and his plan for humanity. It may reveal aspects of God's power, beauty, and order in nature, but it may not reveal his love, mercy, and redemption, which are essential aspects of God's nature that are revealed through divine revelation, such as scripture and religious teachings.
