False Prophets and Wolves in Sheep's clothing are still out there. Always read the bible for yourself and don't blindly believe people's interpretations.
I know very little about the Bible outside of the most common things.
However, I've been able to see a wolf in sheep's clothing since I was a kid. I was born with an obsession for people, so I start reading the characteristics of every person I'm in the presence of.
I have never been wrong. The people I suspected to be thieves ended up stealing something, the people I suspected was soft ended up running from fights. The people I suspected of being reckless ended up catching bodies.
I don't think it takes knowledge of the bible, I think the higher power just gifted some people with those skills and we are supposed to be the leaders in this world.
