I will put both links below, I would advise watching Joel first and then if you should so want to watch the second. For the non Christian or those of no concept of God, satan and such issues, you can either switch off here or take some time to google these issues and see what it comes back with. You can of course leave questions via the comment facility and I will respond there.

1 Thessalonians 5:21 (New Living Translation)
21 but test everything that is said. Hold on to what is good.
