Read Romans 7:18 Using Other Translations
For I know that in me (that is, in my flesh,) dwelleth no good thing: for to will is present with me; but how to perform that which is good I find not.
For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out.
And I know that nothing good lives in me, that is, in my sinful nature. I want to do what is right, but I can’t.
