A commotion broke out at Ashley Madison this weekend after the so-called "adultery website" was hacked. The website's users who have been cheating on their spouses are now terrified that they would be found out. However, American evangelist Franklin Graham is telling them that there is no need for them to run and hide since God already knows about their sins.

"The Bible says, 'be sure your sin will find you out,'" Graham wrote on his Facebook page. "I have news for all those worried cheaters out there wringing their hands—God already knew!"

Hackers threatened to reveal the identities and personal data of the 37 million users of Ashley Madison, the supposedly confidential website which has a slogan that says, "Life is short. Have an affair."

They just leaked the identities of the website's first two subscribers—a man from Canada and the other from Brockton, Massachusetts.

Graham is surprised that immorality has become such a booming business. He noted, however, that even though times have changed, God's laws and standards remain the same. And in the end, people will have to pay for their sins.

Graham then quoted the Bible verse Hebrews 4:13 which says, "Nothing in all creation is hidden from God's sight. Everything is uncovered and laid bare before the eyes of him to whom we must give account."

Dr. Michael Sulmeyer, the director of the Cyber Security Initiative at Harvard's John F. Kennedy School of Government's Belfer Center told CBS News that hackers can get very determined to get into websites that pride themselves on anonymity and discretion to get intimate or embarrassing details. As such, people should be very careful what they do or post online, he advised.

"Even with that, you should not believe that you have total privacy. And if you are really one who wants total privacy then you should not probably be getting on websites like this," Sulmeyer said.
