When I turn my eyes within, All is dark and, vain and wild, Filled with unbelief and sin, Can I deem myself a child? If I pray, or hear, or read, Sin is mixed with all I do; You who love the Lord indeed, Tell me, is it thus with you? Yet I mourn my stubborn will, Find my sin a grief and thrall; Should I grieve at what I feel, If I did not love at all?
