Caught this article on how worship time in prison was a welcome respite from the stress and strain of being and inmate. From my experience I certainly agree with this. I often looked forward to the hour or two on Sunday and the few times we had outside groups come in to worship with us. It was great to be in a positive atmosphere and spend time singing, praising and fellowshipping with other believers.
Some of my best memories are of listening to a band called the Power of Praise. They graciously visited us a few times a year at FCI Elkton. The chapel was usually packed and we sang along with them as they sang contemporary Christian songs and traditional hymns. It was especially emotional at Christmas when they would sing carols like O Holy Night and Silent Night. Man, it tore me up! We had other great groups come in as well. Like the Mennonite Church whose choir performed for us a few times each year. What great voices! So comforting and uplifting.
I encourage you to get involved in worship during your incarceration. It is a welcome respite from the daily struggle.
