John 3:9

Nicodemus answered and said unto him, How can these things be?

Nicodemus answered and said unto him, How can these things be? Though the subject, says Luthardt, still confounds him, the necessity and possibility of the new birth is no longer the point with him, but the nature of it and how it is brought about. From this moment, to use the words of Stier, Nicodemus says nothing more, but has sunk into a disciple who has found his true teacher. Therefore the Saviour now graciously advances in His communications of truth, and once more solemnly brings to the mind of this teacher in Israel, now become a learner, his own not guiltless ignorance, that He may then proceed to utter, out of the fullness of His divine knowledge, such further testimonies, both of earthly and heavenly things, as his docile scholar may to his own profit receive.
