Burdened by sin, rest in Christ

This is a portion of a hymn on prayer, written by John Newton:

With my burden I begin:

Lord, remove this load of sin;

Let Thy blood, for sinners spilt,

Set my conscience free from guilt.

Lord, I come to Thee for rest,

Take possession of my breast;

There Thy blood-bought right maintain,

And without a rival reign.

Vivid images and metaphors are what can make hymns so helpful to our souls. Jesus' blood-bought right to our hearts is gripping.
