“Now is the judgment of this world: now shall the prince of this world be cast out.”
King James Version (KJV)
12:31 Now - This moment. And from this moment Christ thirsted more than ever, till his baptism was accomplished. Is the judgment of this world - That is, now is the judgment given concerning it, whose it shall be. Now shall the prince of this world - Satan, who had gained possession of it by sin and death, be cast out - That is, judged, condemned, cast out of his possession, and out of the bounds of Christ's kingdom.
Joh 12:31 Now is the judgment of this world. "Now", "this hour", the "hour" referred to in Joh 12:23,27. This was the hour for which he had come into the world, the hour of the cross; that was to be the hour of judgment, the crisis, which should determine who should rule the world. The cross became a throne. It gave him the crown. Now shall the prince of this world be cast out. The cross cast him out, dethroned him; he is now a usurper and shall finally be cast into the lake of fire (Re 20:10).
