Friend, can you understand my riddle?

(J. C. Philpot, "Letters & Memoirs")

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?

Is your heart, as my heart?

Alas! Alas! We feel sin's power daily and hourly.
We sigh and groan at times, to be delivered from
the giant strength of our corruptions, which seem
to carry us captive at their will. Though sin is a
sweet morsel to our carnal mind, it grieves our soul.

I am sure I must be a monument of grace and mercy,
if saved from the guilt, curse, and power of sin!

Romans 7:18-25
"I know that nothing good lives in me, that is, in my sinful
nature. For I have the desire to do what is good, but I cannot
carry it out. For what I do is not the good I want to do; no,
the evil I do not want to do; this I keep on doing. Now if I
do what I do not want to do, it is no longer I who do it, but
it is sin living in me that does it. So I find this law at work:
When I want to do good, evil is right there with me. For in my
inner being I delight in God's law; but I see another law at
work in the members of my body, waging war against the law
of my mind and making me a prisoner of the law of sin at work
within my members. What a wretched man I am! Who will
rescue me from this body of death? Thanks be to God, through
Jesus Christ our Lord! So then, I myself in my mind am a slave
to God's law, but in the sinful nature a slave to the law of sin."
