How do we know God is incomprehensible?

The Bible asserts that God exists in a realm beyond complete human understanding. For instance, in Isaiah 46:5, God challenges us to compare Him to anything or anyone, illustrating His uniqueness. Moreover, Job 5:9 speaks of God's unsearchable greatness, emphasizing that we cannot fathom His ways. Throughout the Psalms, such as Psalm 145:3, we learn that God's greatness is unsearchable. Thus, God's nature, wisdom, and purposes exceed human comprehension, underlining the importance of relying on His revelation rather than our own understanding.
