In your struggle against sin and your pursuit of righteousness, may this be of comfort and encouragement to you.

The most theological verse on sanctification is not a list of commandments, but a glorious explanation of how it works and how the Holy Spirit of God is the primarily actor.

2 Corinthians 3:18
And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit.

Walk by the Spirit, and you will not do the works of the flesh, but instead reap the fruit of the Spirit!
