That Camping could know when Christ will return or that James White could know that if Camping seeks to rescue his reputation, he will end up in hell?
James White: "I fear if you seek to rescue your reputation, you will end your life under the wrath of God. Your unwillingness to listen to counsel has already caused great damage to the cause of Christ. You have one final chance for redemption, sir. Do not remain stiff-necked. Repent and turn from your ways." (link)
