a puritan prayer

i was deeply convicted by a prayer of confession dubbed "The Precious Blood", which we read as part of a weekly service at my church recently. some of it is below:

Sin is my malady, my monster, my foe, my viper,
born in my birth,
alive in my life,
strong in my character,
dominating my faculties,
following me as a shadow,
intermingling with my every thought,
the chain that holds me captive in the empire of my soul.

Sinner that I am, why should the sun give me light,
the air supply breath,
the earth bear my tread,
its fruits nourish me,
its creatures subserve my ends?

Yet your compassions yearn over me,
your heart hastens to my rescue,
your love endured my curse,
your mercy bore my deserved stripes.

Let me walk humbly in the lowest depths of humiliation,
bathed in your blood,
tender of conscience,
triumphing gloriously as an heir of salvation.
