The lyrics of this song come from Psalm 40 (sing a new song) and Matthew 6 (the Lord’s prayer) as penned by Catholic singer/songwriter Matt Maher (http://mattmahermusic.com) in collaboration with Ed Cash (accomplished singer/songwriter/songcompleter in the christian music/worship realm).
In the process of writing and rewriting this song, Maher writes that he hopes that this song can be one that emphasizes the unity of the Christian faith as all traditions utilize some form of the Lord’s prayer as found in the Sermon on the Mount in Matthew 5-7.
It gives me hope for the future of church music (and the church) when worship leaders and musicians use ancient words with modern arrangements that have such a high degree of liturgical and practical significance–such as this song. This gives me hope–hope that the Church can move beyond the extremes of traditionalism (tradition for its own sake) and the misunderstanding/denial of traditions & people who have come before us. I have hope that the Church can 
continue to express the Christian faith in ways that embrace the ancient, liturgical, & traditional elements of our past while engaging with the modern/post-modern/future elements of our current cultural climate and our contextual understanding of Christianity. Music and worship like what Matt Maher and Marty Reardon (see post below) are doing is giving deeper context and meaning to ancient liturgical words and practices that enable people to gain a deeper understanding of the Christian faith and tradition. May others continue to do so.
Maher is also the author of the popular song “Your Grace is Enough.” One of my favorites from the album “Alive Again” is a deep, meaningful, & liturgical song: “Christ is Risen From the Dead”, which uses the Eastern Orthodox phrase from the Pascha (Easter) “Christ is risen from the dead/trampling over death by death.” It will likely show up here later this liturgical year.
