It's a prophecy about the kingdom of Israel when God dwells there. So when God lives in Jerusalem no false prophet will ever set foot there. If you read previous chapters you see that God is telling Ezekiel His plan for Israel. Many of the Israelis are complaining that God isn't going to fulfill His promises that He gave to Israel. But He promises to bring them all back one day, even resurrecting the dead and bringing them back.
So plenty of false prophets can currently enter Israel and Jerusalem today. God doesn't live there. The dead haven't been resurrected. Until that happens "prophets" can make up all the lies they want and still enter Israel today.
The Message of Baha’u’llah has given us other ways that we can look at these passages.
Abdul'baha offered this, "God is pure perfection and the creation is absolute imperfection. For God to descend into the degrees of existence would be the greatest of imperfections; rather, His manifestation, dawning, and effulgence are even as the appearance of the sun in a clear, bright, and polished mirror."
This means the Messengers, such as Christ, Muhammad and Baha'u'llah, to name a few, become the 'Self of God', the focal point of all the knowledge we have about God and an example.of all the Attributes given by God to humanity. Thus God dwelling with us, are the representatives given by God, the "Annointed Ones" the true Prophets. Only they are the true Prophets.
Christ, Muhammad, the Bab and Baha'u'llah, Abraham, Moses all reside in Israel , and as they are all One with all of God's other given Messengers, such as Zoroaster and Krishna, God rules from Israel via all those God given Names and Attributes.
The dead have arisen, this rising of the dead is not of the flesh, but that is a deviation from this OP.
Can you name a prophet that is established in Isreal, that has revealed scriptures, that I have not mentioned above?
