I’ve always wondered what it means in the bible about a dog returning to its vomit.   Proverbs 26 : 11

I’m guessing its to do with patterns of sin we often fall into.

In the last year I’ve seen actors and pop stars find the Lord, but later they get back into the drugs and a previous lifestyle only later.   Some Christians have some kind of background in new age before they are saved, and I worry when later they think it won’t hurt try Reiki (founded in Bhuddism) or hypnotism or reflexology (not recognised by mainstream medicine)

This blog article seems to cover this very well:-
