'Understood' in the Bible

None of the rulers of this age recognized and understood this wisdom; for if they had, they would not have crucified the Lord of glory;

For who has known the mind and purposes of the Lord, so as to instruct Him? But we have the mind of Christ [to be guided by His thoughts and purposes].

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].
