Growing up, my parish priest and the cantor would sing a stunning rendition of O Holy Night at the Christmas vigil mass that was amazing.
I really love some of the stripped down acoustic versions of the songs “Oceans”, “Touch The Sky”, and “Say The Word” by Hillsong United. I have heard them played during praise and worship style Adoration before and they were really moving. Their Album “Of Dirt and Grace: Live From The Land” has really intimate versions of these songs being performed at various locations in the Holy Land.
Another good one that moved me in prayer during Adoration was “It Is Well” by Bethel Music. I heard it at a conference, played by Ike Ndolo and Sarah Kroger and was the best version of it I have ever heard.
