'Imperfectly' in the Bible

For now [in this time of imperfection] we see in a mirror dimly [a blurred reflection, a riddle, an enigma], but then [when the time of perfection comes we will see reality] face to face. Now I know in part [just in fragments], but then I will know fully, just as I have been fully known [by God].

By people who live on milk I mean those who are imperfectly acquainted with the teaching concerning righteousness.
