Romans 7:19-21

Amplified Bible, Classic Edition

¹⁹ For I fail to practice the good deeds I desire to do, but the evil deeds that I do not desire to do are what I am [ever] doing.

²⁰ Now if I do what I do not desire to do, it is no longer I doing it [it is not myself that acts], but the sin [principle] which dwells within me [^[a]fixed and operating in my soul].

²¹ So I find it to be a law (rule of action of my being) that when I want to do what is right and good, evil is ever present with me and I am subject to its insistent demands.
