La música cristiana es de origen judío: la liturgia musical de la sinagoga, en particular el canto psalmódico de los judíos como unidad poética musical, fue un legado preciado transmitido del Israel antiguo al cristianismo primitivo, como forma de manifestar tanto a nivel personal como comunitario las creencias religiosas y la fe en Dios.
Investigate my life and make me clean
Shine upon the darkest place in me
To you my life's an open book
So turn the page and take a look
Upon the life you've made
Always, my days, I'll praise
Fly away, where heaven calls my name
Fly away, I'll never be the same
Investigate, I can't wait
Excavate, recreate
Investigate my life and take me through
Shine upon the road that leads to you
I know you'd heard the words I'd say
Before I'd even lived one day
You knew the life you'd made
Always, my days, I'll praise
Investigate my life and make me clean
Shine upon the darkest place in me
When I go, when I return you've seen your holy fire burn
Upon the life you made
Always, I'll praise
