Still, God wasn't done allowing Level to experience the depths of depravity gang life can offer, and his life was to be threatened, and miraculously spared, several more times.
"I remember the time the gun jammed in my face," he shared. "I remember the time the bullet grazed my head. The other time the bullet whistled by my ear. The times I was running through the backyard and they were shooting at me. All the times I got shot at. All the times I was half-dead, but I was still alive."
Later on in life, and after starting a family, Level traded a life of criminal violence for a career in professional violence as a mixed martial arts (MMA) fighter.
"I was always good at fighting," Martinez explained. "I started fighting bare-knuckle with Kimbo Slice. I was beating everybody bare-knuckle; we're betting money in the backyards, bare-knuckle, I'm winning."
"My name got so big that Telemundo came and they offered me a pro contract," he added. "I went to Nicaragua beat the three-time world champion, Ricardo Mayorga."
Even though Level had abandoned the criminal life, he was still a spiritually-dead man walking: "I had the money. I had the fame. I was doing the gangster music. But I was empty inside."
But, like so many sons, he was reached by the power of his mother's prayers after she herself became a Christian.
Finally, in 2016, Level had a radical encounter with God that literally brought him to his knees. "It's like he showed me my whole life in a matter of like five seconds," he said.
"I just got on my knees. I started crying out to God. And when He spoke to me, I knew that if I didn't surrender, I felt like I was going to die."
Now, just over two years later, Level is back on the streets, but not as a thug spreading violence and fear. Now, he's "giving them life..."
"Now I'm giving them Jesus," he said. "I tell them 'repent and be baptized in the name of Jesus Christ for the remission of sins and you shall receive the gift of the Holy Ghost', Acts 2:38. That's what I preach."
Level's incredible ministry, which has a heavy focus on reaching criminals and gang members with the saving power of the gospel of Jesus, has already begun to bear fruit: "A lot of people come to Christ cause of my testimony and I'm just honored to be used by God."
"It's a privilege and honor to be used by him. He could have chosen anybody else," he said. "I could have been one of the people that died early. But I'm still here and I'm grateful."
