Plenty of refrences in the bible to sheep, flocks, etc.

All humans are some sort of sheep to the Lord.

Well, sheep are usually raised for a purpose? Go to a County Fair and look at the livestock.

So, when you are raising sheep, you keep the good ones, and get rid of the bad ones. This is basicaly what the Lord has in store for us all.

Certain Demonic entities, who are destined for destruction (and they know it) will try to attach, entwine, and parlay a chance at survival by embeding itself into other cultures chromazone structure?

"Do not give that which is Holy unto Dogs, Niether should you cast pearls before Swine, lest they trample them under their feet and turn again and rend you."

Noah, a man "righteous in his generation," to build an ark and save a remnant of life from the Flood.

Jesus had the parable of the Wheat and the Darnel.
"But master you sowed good seed here, yet there is darnel (chaff) among the wheat? An enemy has done this"

Do what you will, and do so at the risk of the extermination of your Holy Spirit?
