Romans 7:21-23

²¹ I find then a law, that evil is present with me, the one who wills to do good.

²² For I delight in the law of God according to the inward man.

²³ But I see another law in my members, warring against the law of my mind, and bringing me into captivity to the law of sin which is in my members

law (verse 21) — probably referring to the principle laid out in the rest of the verse, but perhaps to the Mosaic Law

law (verse 22) — the same as “the law of my mind” in verse 23.

law in my members (verse 23) — principle that evil is present despite the desire to do good.

mind = new nature (in contrast to the flesh)

law of sin (verse 23) — the “another law” earlier in the verse
