A Christian ministry brings the gospel to prisoners incarcerated for 10 years to life in prison and shares how the spirits of these men have changed.

God Behind Bars is a ministry that has partnered with churches and other faith-based organizations across the U.S. since 2009 to transform the lives of prison inmates and their families by introducing them to God, developing a relationship with the Lord and helping them reestablish themselves into society once released.

On July 7, God Behind Bars released a video on their social media platforms showing the impact they have on prison inmates. 

"IN PRISON, 100 inmates went CRAZY in worship!" says God Behind Bars on Instagram. "BUT WAIT...An inmate picks up the mic and begins to sing! This man singing has been in prison for 18 years and is an incredible worship leader. This inmate found Jesus in prison and now helps lead THOUSANDS of incarcerated men to faith in Jesus!"

In total, there was 150 inmates who gathered inside the prison chapel to listen to a speaker and participate in praise and worship.

"Some of you guys in this room—this is one of the only moments that you just have your time with the Lord," says the speaker in the full YouTube video. "It might always be chaos or noise...so I just want to take a moment and allow you guys...to just spend some time with Jesus, reflect, begin to think of things that you're grateful for."

As worship music filled the rooms, hands are raised, inmates start jumping and cheers are let out.

"As we began to play 'Gratitude' by Brandon Lake, the spirit of the men worshipping changed," says the video description. "These incarcerated men began to cheer and clap as they sing 'So come on, my soul, Oh, don't you get shy on m, Lift up your song, 'Cause you've got a lion inside of those lungs, Get up and praise, the Lord.'"
