You read it too quickly. Read what I added.
Yes. I did read it. Your mortal body is sentenced to death because of sin. Therefore while you are in your mortal body the presence of sin is still with you.
Are you saying you have no desire to sin? Really? Let's look at the works of the flesh:
"The acts of the flesh are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; drunkenness, orgies, and the like" (Galatians 5:19-21_.
So since you were converted to Christ:
You have never had a lustful or impure thought;
You have never read a horoscope, ouija board, or anything else of the occult, even something minor like tricking or treating at Halloween;
You have never got angry at anyone;
Never been contentious;
Never involved in a clique or faction of any kind;
Never had even a small thought of envy concerning anything that anyone has that you haven't got;
Never been jealous of anyone who has been in a role that was denied to you;
Never chosen selfish actions in any way;
Never got drunk;
Never watched movies or TV programmes that involve impurity, violence or godlessness;
Never had even the slightest judgmental thought about anyone;
Never been thankful that you are not like someone who has been immoral or sinful.
It is not just the outward actions, but there are thoughts and attitudes of the heart that can involve temptation and a falling short of sinless perfection.
These are the struggles and pressures we all have, including you if you are to be realistic about yourself, while we are in this mortal body.
