Regarding the understanding of God as essence:

We already know that judging humans based on their jobs, titles, abilities, or wealth is not love. Consider the idea of judging people and wanting to marry based on such categories.

An important point to note here is that love and understanding or comprehension are fundamentally different. God cannot be understood merely as an object of cold observation outside of the relationship of love. If we cannot know a person deeply without love, how can we come to know God without love?

But, we have established theology that seeks to explore the essence of God through cold rationality. Is God, God, because He is omniscient, omnipotent, omnipresent, and always good? Attempts to judge God based on concepts understood outside of love for God will never succeed.
