Friend, can you understand my riddle?

I find that sin has such power over me, that though I call on the Lord again and again for deliverance, I seem to be as weak as ever when temptation comes. If a window were placed in my bosom, what filth and vileness would be seen by all. "O you hideous monster sin, What a curse, have you brought in!" I love it; I hate it. I want to be delivered from the power of it; and yet am not satisfied without drinking down its poisoned sweets. Sin is my hourly companion; and my daily curse. Sin is the breath of my mouth; and the cause of my groans. Sin is my incentive to prayer; and my hinderer of it. Sin made my Savior suffer; and makes my Savior precious. Sin spoils every pleasure; and adds a sting to every pain. Sin fits a soul for heaven; and ripens a soul for hell. Friend, can you understand my riddle?
