First, Mr. Lemieux and all, welcome to the human race, which, as Saint Paul notes:
“. . . all [of us, you and me, every and all humans, no exceptions but by God’s powerful and special graces, the tabernacle vessel of Mary’s person and body] have sinned and fall short of the glory of God (Romans 3:23)

He goes on in Romans about his own sinful nature, having picked up more on the disordered abuse of the goods within the Commandments simply by knowing what the Commandments would stop him from doing. He is confounded even in his will by the sin he knows. Do let us remember that God gave the Israelites and us (me) the Commandments because I just have not quit my disorders in my sin. Let us not blame God or His law because it is we – I! – who caused Him to state them. (And, let’s face it – if I were the only sinner of all humanity, and He came to die to save me, first He would have given me His law to give me help along my sinful way out of my sinful way – if you get my meaning: that God’s helps are always holy and salvific.)

That is to say, as Saint Paul has it in very assimilable first-person:
. . . if it had not been for the law, I should not have known sin. I should not have known what it is to covet if the law had not said, “You shall not covet.” But sin, finding opportunity in the commandment, wrought in me all kinds of covetousness. Apart from the law sin lies dead.
I was once alive apart from the law, but when the commandment came, sin revived and I died;
the very commandment which promised life proved to be death to me. [??!!]
For sin, finding opportunity in the commandment, deceived me and by it killed me.
So the law is holy, and the commandment is holy and just and good. (Romans 7:7-13) [That is to say, by my nature, I am sinner for taking to that which is prohibited within the Commandments, only by sinful disorder in me due to my originally sinful nature.]
Saint Paul goes on: We know that the law is spiritual; but I am carnal, sold under sin. For I do not do what I want, but I do the very thing I hate. Now if I do what I do not want, I agree that the law is good. So then it is no longer I that do it, but sin which dwells within me. (verses 14-17)
For I do not do the good I want, but the evil I do not want is what I do. (verse 19)
Now if I do what I do not want, it is no longer I [that best “I”] that do it, but sin which dwells within me. So I find it to be a law that when I want to do right, evil lies close at hand. For I delight in the law of God, in my inmost self, but I see in my members another law at war with the law of my mind and making me captive to the law of sin which dwells in my members. Wretched man that I am! Who will deliver me from this body of death? [Who else?] Thanks be to God through Jesus Christ our Lord! (Romans 7:20-25)

I cannot find the ‘best of me’ until I find Christ Jesus, Who awaits my closest touch with Him there. After all, praised be our God, the very Mass and Eucharist witnesses with a mystery of profound simplicity that Jesus just loves to deliver His graces very personally.

And, to all, may you find Jesus, and with Him who He means for you to be.
My Lord and my God, of Your love, be pleased to guide us all to Yourself.
