We have seen before in the 10th chapter that Israel will return to idolatry in the last days. The unclean spirit of idolatry which was cast out will at last return with seven others and will find the house empty, swept and garnished. And the evil spirit, with the seven others more evil than himself; will enter in and dwell there, so that the last state of Israel becometh worse than the first. This will happen to this evil generation. This section of the 13th chapter makes it very clear that when the fountain is opened against sin and uncleanness, that idols will have been in the land, and false prophets prophesy there immediately before the manifestation of the Lord from heaven; for how could the names of the idols be cut off from the land if there were none there? Palestine may well be put down now as the great centre of false worship. Greek and Latin crosses are seen on all sides in Jerusalem and other places, while saints, holy houses and places are worshipped and adored. On the spot where the Lord's house stood, there stands to-day the mosque of the false prophet. All is idolatry. Of course when the Lord returns these false temples will be destroyed, and the Greek and Latin idolatries, as well as Islam, will forever pass out of existence. There will be a purging of the land from these abominations. This may be included in the prophecy here. Still, it is the people of Israel who are especially concerned in the prophecy before us. The land has often been the scene of idol worship, and the people engaged in that which Jehovah despises. It will be so again, only in a much worse form, when false prophets who are inspired by the unclean spirit, and demons themselves will be their guides. We must look to Revelation for a key. It is well known to all students of the prophetic word that all which comes after the third chapter in the last book of the Bible is future still. We are yet in the things which are present. When the Lord has taken the Church to Himself then the great visions, tribulations, wrath and judgment will be fulfilled. Aside from the scenes in heaven we learn from Revelation the events in the earth during the great tribulation which ends with the wrath from heaven.
