John 16:31

Jesus answered them, Do ye now believe? Behold the hour cometh, yea, is come, that ye shall be scattered, every man to his own, and shall leave me alone: and yet I am not alone, because the Father is with me.

Do ye now believe? ... is not a questioning of their faith, which was genuine enough; but it was a warning against overconfidence. The Old Testament prophet had written, "Smite the shepherd, and the sheep shall be scattered" (Zechariah 13:7), and Mark (Mark 14:27) identified the scattering of the apostles during the Passion as the fulfillment of that prophecy. There is infinite pathos in these words. The scattering of the apostles, the smiting of the Shepherd, the Saviour's being left alone, and his comment that he would not be really alone, for God was with him - the thoughts that tug at the heart as one contemplates such events on the night of our Saviour's Gethsemane with the cross looming on the morrow are wholly tragic. Utterly no human consolation would be available for the Son of God when he would "tread the winepress alone" (Isaiah 63:3) to redeem men from sin.
