As a teenager, he was a violent, murderous gang member, then a woman put him on her 'hit list.' Now he's a pastor and a family man.

Casey Diaz was once a gang member and murderer who took pleasure in the violence and chaos that was inherent to his lifestyle — until an encounter with the Bible's message of hope changed his life in the most profound ways imaginable.

Diaz, who tells his life-affirming story his new book, "The Shot Caller: A Latino Gangbanger's Miraculous Escape from a Life of Violence to a New Life in Christ," recently appeared on PureFlix.com's "Pure Talk" to reveal the ins and outs of his unlikely transformation.

The former gang leader said life started to get complex after he and his family immigrated to America from El Salvador when he was just 2 years old. By the time he was 8, familial chaos raged, with drugs and alcohol entering the home and his mother facing abuse from his dad. 

"It's one of those things that no kid should ever see," Diaz said of the violence.

Watch Diaz share his transformation from violent gang leader to Christian pastor:

In addition to fighting in the home, Diaz saw extreme violence in the streets, recounting a truly disturbing moment he observed as a child.

"It was a normal broad daylight day and a guy in this alley parked his car, walked over to three guys … and gunned them down, all three of them," he said. "You're seeing violence in your apartment and your family, and then you're seeing violence in your alley."

All of this added to the "perception that life is cheap" and that harming someone else is "no big deal." With these tragic ideas taking root, Diaz joined a gang by the time he was 11 years old — a decision that led him on a truly destructive path.

"That was the beginning of a rough road in violence," he said.

It started with stabbing a rival gang member and, over time, committing even more serious crimes, as Diaz was overtaken by the criminal life he had entered into.

"You start to enjoy it, and it sounds sick because it is," he said. "But you really enjoy partaking in the violence of it."

As Diaz entered his teen years, he was in and out of courts and jail — until another more serious crime sealed his fate.

"At 16 years old, I committed murder and I was a fugitive for 21 days," he said. "I was caught by the Los Angeles Police Department … I was captured and arrested."

Diaz ended up continuing his gang activities in prison, landing himself in solitary confinement. But when a Baptist church started visiting the prison and a woman asked if she could approach his cell, Diaz had no idea how much his life would change.

"She came in there and asked the guards to approach my cell," he said. "She said, 'I'm going to pray for you. I'm going to put you on my 'hit list.' I'm going to pray for you. … and Jesus is going to use you.'"

He recalled thinking, "This lady is nuts," but over the course of the next year, she continued coming, and Diaz 
eventually had a life-altering moment that forever changed his trajectory.

"I had a moment … where Christ [made] himself very real in my cell," he said. "I knew for a fact that I had sinned before God. That became the pivotal point of change for me."

Diaz accepted the Christian faith and was eventually released from prison. Today, he's married, has three kids and is the pastor of a church in Burbank, California.

He shares his story of remarkable life change through speeches and his "The Shot Caller" book. It's a story that shows the true power that God can have over the human life and heart.

"That's what Christ does in the life of anybody," he said of God's power to transform.
