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.
Mercy speaks by jesus' blood
Hear and sing, ye sons of god
Justice satisfied indeed
Christ has full atonement made
Jesus' blood speaks loud and sweet
Here all deity can meet
And, without a jarring voice
Welcome zion to rejoice
(chorus)
"all her debts were cast on me,
And she must and shall go free"
Peace of conscience, peace with god
We obtain through jesus' blood
Jesus' blood speaks solid rest
We believe, and we are blest
(chorus)
(bridge)
Should the law against her roar
Jesus' blood still speaks with power
"all her debts were cast on me,
And she must and shall go free"
