Romans 7:21

Εὑρίσκω ἄρα τὸν νόμον τῷ θέλοντι ἐμοὶ ποιεῖν τὸ καλόν, ὅτι ἐμοὶ τὸ κακὸν παράκειται.

Eyriskō ara ton nomon tō thelonti emoi poiein to kalon, oti emoi to kakon parakeitai.

King James Version (KJV)

I find then a law, that, when I would do good, evil is present with me.

Modern English

So I find this law at work: Although I want to do good, evil is right there with me.
