Brother you are on the right track, you realize you have sin in your life and are acknowledging it or bringing it to light. Most new believers like me, think they are sinless. I remember thinking I was not sinning, because I thought sin was the act and not the thought of sin. Here's a Scripture that helped me, but you already have it in practice, very mature.
I John 1:8-10 "If we say we have no sin, we deceive ourselves, and the truth is not in us.9 If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.10 If we say we have not sinned, we make him a liar, and his word is not in us."
The word "confess" here in first John means to agree. So if we agree with God that we have sin He is faithful and just to forgive us our sins. Like I memntioned Brother you are on the right track and are not grieving the Holy Spirit by confessing your sins.
You seem to be setting your mind on the things of God or the things of the Spirit.
Romans 8:1-6 "There is therefore now no condemnation for those who are in Christ Jesus.2 For the law of the Spirit of life has set you free in Christ Jesus from the law of sin and death.3 For God has done what the law, weakened by the flesh, could not do. By sending his own Son in the likeness of sinful flesh and for sin, he condemned sin in the flesh,4 in order that the righteous requirement of the law might be fulfilled in us, who walk not according to the flesh but according to the Spirit.5 For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit.6 For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace.7 For the mind that is set on the flesh is hostile to God, for it does not submit to God's law; indeed, it cannot.8 Those who are in the flesh cannot please God."
I see the Spirit working in you, so keep growing as you are Brother, let the Spirit led you and guide you in the way of the Lord. God Bless my Brother, I wish I was as muture as you are when I was a new believer.
