In Oprah Winfrey's Belief series, Lenny Kravitz shares his spiritual encounter with God - an incredible moment that happened to him way before his success.

When he was younger, the Grammy winner was a member of the California Boys Choir, which was one of the most prestigious choirs in the world.

Although the future rock star was not raised by particularly religious parents, the son of a Jewish father and a Christian mother was able to feel the presence of God on his own.

Recalling his story, rigorous rehearsals weakened the young choir member's resistance.

"I got sick. I had the flu and I got sent to this infirmary where this other kid was," Kravitz told Oprah. "He and I were in this room together for days, getting checked on and getting better."

Alone in the room with his new buddy, Kravitz found himself in a spiritual conversation with the boy.

"He's like, 'Do you know about Jesus Christ?'" he recalled. "I said, 'Well, I've heard of him, but what?'"

"He starts telling me all about Christ and all this scripture and things, just talking to me and reading to me," he continued. "It's quite interesting because you have these two young boys just sitting there talking and having this great conversation about God and love and Christ."

As their conversation deepened, both young boys felt a sudden unexplainable feeling.

"I can't explain it to you, but the presence of God was in the room," Kravitz said. "I'm talking about something really heavy and thick, and the two of us felt it. It was something that just kind of came over us. We were both crying because whatever this presence was, was so overwhelming that it just hit you in your spirit... We were having an experience with God."

"The spirit, the being, the power that created me was right there with me," he added. "I didn't need to go to anybody to deal with God. It was just right there. It was a personal experience."

That moment for Kravitz kept his belief in God strong through the years.
