How to politely tell a family member I'm not worried about the second coming of Christ?

My aunt is a wonderful lady, but she's very gullible. Thanks to a video she saw on Facebook, she now believes the conflict in Israel is a sign of the end times and is deeply concerned for my immortal soul. How do I politely let her know that while I appreciate her concern I have no real reason to believe that the Israeli government commiting war crimes against Palestine is going to bring about the second coming of Christ?
