'In Me' in the Bible

What follows, then? That 'the Law is equivalent to sin'? Never! Why, had it not been for the Law, I would never have known what sin meant! Thus I would never have known what it is to covet, unless the Law had said, You must not covet.

That being so, it is not I who do the deed but sin that dwells within me.

For in me (that is, in my flesh) no good dwells, I know; the wish is there, but not the power of doing what is right.

Well, if I act against my wishes, it is not I who do the deed but sin that dwells within me.
