Former 'Pop Evil' star Tony Greve recently shared his testimony about God saving him from a world of sin, highlighted by him casting out a demon out of his own brother's body.

Greve was formerly the lead and rhythm guitarist of the hard rock group from 2007-2012, where the band released hit songs such as "Hero," "100 in a 55" and "Boss's Daughter" to name a few.

"I'm playing in these venues; I'm touring with Judas Priest. That's crazy, you know what I mean? I'm getting to do all this stuff, and so there's almost, in one sense there's an emotional high about that. You're like, 'Wow, this is the stuff that I dreamed of doing and I'm doing it. I'm getting to live it'," said Greve to CBN in an interview.

"For me it was an identity thing. This is who I am, I'm Tony Greve; I'm the guitar player of Pop Evil. This is what I do. It becomes your identity. I think that scares people. Who would you be, if you weren't you? There's an emptiness because it's not what you thought you'd be. The bigger the band got, the emptier... It felt like you were just walking into a black hole going deeper and deeper into darkness... And at this time, I remember crying out to God-who else are you going to cry out to? But people began to come into my life."

Greve then revealed that a few days after a pastor prayed with him he had a supernatural encounter with God several years ago.

"I said, 'There's nothing different, but I believe in You. I said 'God, Why is this still hard?' And I heard God speak to me so crystal clear, He said, 'I created you for a relationship with Me. It'll never work without Me.' And this was the thing: I'd never repented," said Greve.

"I'd never repented of my sins, and for the first time in my life, I felt the Holy Ghost convicting me about my sins. So I began to just confess my sins out to God and as I did, I broke. I mean something in me broke. I just-it was like I fell into His arms."

However, because of bad advice from his father convincing not to give up the fame and the money, the rocker continued to backslide into the lifestyle of sex, drugs and alcohol.

But that changed one day after a friend convinced him to use the Satanic Ouija board, which resulted in his brother getting possessed by a demon.

"...My brother cries out and this thing enters his body. And it just kind of flies him back to the ground. I remember stepping back and just being terrified. He turned and looked at me. I had never experienced that much hate in all of my life to see this thing looking at me through my brother. And the Lord spoke to me and said, 'it's going to be you or him.' And again, he brought that Scripture back to mind, '9:26. 9:26, cast out that devil, boy!'

"And all of a sudden I felt boldness hit me, and I remember I just jumped over my brother and palmed his head and took authority over that devil. It was like it lost all power immediately. Just gone. His head shot back, his eyes rolled back. I mean, he just-this thing convulsed at the name of Jesus."

After that experience, he re-dedicated his life to Jesus for good and he now plans to become a minister.

"I didn't know who I was before. Even though, yeah, I was Tony Greve of Pop Evil. Yeah, I had all those things. There was this emptiness of this not knowing, this un-belonging," said Greve.

"And knowing, you know, that God is real, that God is my Father, that I have a relationship with Him. There's no greater fulfillment than that."
