Lord Jesus, think on me and purge away my sin;
From earthborn passions set me free and make me pure within.

Lord Jesus, think on me, with many a care oppressed;
Let me Thy loving servant be and taste Thy promised rest.

Lord Jesus, think on me amid the battle's strife;
In all my pain and misery be Thou my Health and Life.

Lord Jesus, think on me nor let me go astray;
Through darkness and perplexity point Thou the heavenly way.

Lord Jesus, think on me when floods the tempest high;
When on doth rush the enemy, O Savior, be Thou nigh!

Lord Jesus, think on me that, when the flood is past,
I may th'eternal brightness see and share Thy joy at last.

Lord Jesus, think on me that I may sing above
To Father, Spirit, and to Thee the strains of praise and love.
