My question is why are there so many false teachers out there that saying that the devil is not real.....?

I've already said, Devil get behind me, twice today. He has been challenging my faith since I started going back to church. He's real unfortunately. Keep up the faith.

When there is so much proof in existences that shows that the devil and his demonic hoard are all to very real......... Also the bible shows us that mankind is more than powerful enough to defeat the devil and his demonic hoard at any given moment.... So why? are the people using the gifts that God has made available for every one....... Also why did the Holy Roman Catholic Church remove The Rites of The Exorcism from the Bible and change it so that only they can utilizes it and now they don't want to utilizes to help any one that is not Catholic............................

The devil works best in secret.

because of Secular Humanism - a very influential sinister society that wants to stamp out Christianity - it denies the existence of ghosts , demons and God

They're entitled to their opinion even if you disagree with them fully. I guess they just say what they believe and others can do the same.

It's the biggest deception of all..he doesn't exsist. Ha.

Because he is not. The only "false teachers" are those that push religion.

They enjoy a chaotic society..until it inconveniences them

Because it's true,I am not real.
