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.
Someone's knocking at the door
Someone's knocking at the door
Can you hear Him knocking
Can you hear Him knocking
He's been knocking very long
He's been knocking for so long
Can you hear Him knocking
Can you hear Him knocking
Jesus Jesus Jesus, is at the door [x2]
Someone's calling out your name
Calling time and time again
Can you hear Him calling
Can you hear Him calling
He's been calling very long
He's been calling for so long
Can you hear Him calling
He's been calling you
It's Jesus Jesus Jesus, is at the door [x2]
Don't let him walk away
He's so patient but, don't take a chance
All you need to do is open the door
Let Him take his rightful place
So He can change your world
Open up the door... [x18]
