Drawn to the cross, which Thou hast blessedWith healing gifts for souls distressed,To find in Thee my life, my rest,Christ crucified, I come.
Thou knowest all my griefs and fears,Thy grace abused, my misspent years;Yet now to Thee with contrite tears,Christ crucified, I come.
Wash me and take away each stain;Let nothing of my sin remain.For cleansing, though it be through pain,Christ crucified, I come.
And then for work to do for Thee,Which shall so sweet a service beThat angels well might envy me,Christ crucified, I come.
