Not but bought

Not what my hands have done Can save my guilty soul;
Not what my toiling flesh has borne Can make my spirit whole.
Not what I feel or do Can give me peace with God;
Not all my prayers, And sighs and tears Can bear my awful load.

Thy work alone, O Christ, Can ease this weight of sin
Thy blood alone O Lamb of God, Can give me peace within.
Thy love to me O God, Not mine, O Lord, to Thee
Can rid me of This dark unrest,And set my spirit free!

Horatius Bonar
