The answer from God’s word:
“God and man cannot be spoken of as equals. His substance and His work are most unfathomable and incomprehensible to man. If God does not personally do His work and speak His words in the world of man, then man would never be able to understand the will of God, and so, even those who have devoted their entire life to God would be incapable of gaining His approval. Without God’s work, no matter how good man’s doing, it will count for nothing, for the thoughts of God shall always be higher than the thoughts of man, and the wisdom of God is unfathomable to man. And so I say that those who have ‘seen through’ God and His work are ineffectual, they are all arrogant and ignorant.
