What does the Bible say about God's purpose in asking questions?

In the book of Job, God continuously questions Job to highlight Job's limitations and pride. God asks, 'Canst thou?' to demonstrate that as humans, we are not in control of our circumstances or even our understanding of Him. This serves to humble us before His mighty hand and make us aware of our inherent sinfulness, which we often overlook when we cling to our own righteousness. God's intent in asking these questions is to prepare us for His grace and to magnify His power in our lives, showing that we must rely on Him and not our own strength.
