Jesus asks. How do we answer?

One of the passages in scripture that always gives me a heartache is Jesus lament, "When I return will I find any faith on the earth?" Did He ask that question literally? As God He certainly knew how many would be faithful when He returned for the general judgment. Was his question rhetorical - expressing His pain at the loss of any of His children? Does Jesus' question call for a response from us? What should that response be? These are questions that I want to reflect on so I can give Him an answer. If he asked you that question, how would you respond?
