How long (love constraining to obedience)

To see the law by Christ fulfilled, to hear His pardoning voice
Can change a slave into a child and duty into choice
No strength of nature can suffice to serve the Lord aright
And what she has she misapplies for want of clearer light

How long, how long beneath the law I lay
How long, how long I struggled to obey

Then to abstain from outward sin was more than I could do
Now If I feel its power within, I feel I hate it too
Then all my servile works were done, a righteousness to raise
Now, freely chosen in the Son, I freely choose His ways

How long, how long beneath the law I lay
How long, how long I struggled to obey
How long, how long in bondage and distress
How long, how long I tried without success...
