A.T. Robertson Commentary John 16:31

"Jesus answered them, Do ye now believe?" — John 16:31 (ASV)

Do ye now believe? (αρτ πιστευετε; ). For αρτ (just now) see 9:19; 13:33,37. Their belief in Christ was genuine as far as it went, but perils await them of which they are ignorant. They are too self-confident as their despair at Christ's death shows.
