Whether you believe this "Kryon" thing is demonic, or just sadly misguided, you should remember that it is a cult, preying on those who are vulnerable.
It's easy to scoff at names such as "Lightworkers" "Indigo Children" and so on, but vulnerable people are taken in by this nonsense.
Cults, whether demonic, satanic new age or even "so-called" Christian are an abomination, an affront to God and a distortion of morality. Hence is is every good Christian's duty to challenge and expose them for what they are.
