Popular discourse on demons and devils are that they are part of the unseen underworld at the command of the devil.
However, Jesus depicts them a little differently that usually described.
He describes them as MEN !
John 8:44 Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.
In fact, these guys were the religious leaders of the day, not some weird unseen force that jumps from body to body and one that takes over souls.
I could go on much more into this but most would be nothing more than speculation, but yes, with Biblical roots.
However, my emphasis here is that while the Devil is not exactly a good guy, where we place all blame on HIM, the fault of our own properly belongs to us.
That means, that men may attempt to guide and educate us, it is our proper role to assume responsibly to our self.
Those dark unseen forces are at least the lusts and desires of the heart which are mostly unseen to the ordinary man.
However, our own nature is more or less inclined to yield and to follow those evil desires as the basis of our flesh is about the same: it is centered in sin.
Thus our task is to resist the devil, but also to make sure our own heart is in order and in alignment with God.
Our inclination to blame the devil for all our woes and behaviors are erroneous and clearly Jesus stated they were nothing more really than the words and pleasures of MEN.

I’m with you! Many times we blame the devil and give him “credit” for our own wrong-doings! We need to look at ourselves and take ownership of our desires to do the wrong things. Preach it brother!

Tom, your words teased another thought I have had from time to time. The “I give God all the Glory” – the “without Him I am nothing” we are taught to think is “good following”.
Both sides – the “not me good” and “not me bad” always seem more “victim mentality” than anything else. And I don’t see that teaching anywhere in the bible.
