The eternal that speaks of the eternal land the New Jerusalem to begin with...
You will have a hard time finding "the eternal land the New Jerusalem" in the Bible.
1. It is a Heavenly city, not a land. The land of Israel will be on earth stretching from the Nile to the Euphrates.
2. It is 1500 miles long, 1500 miles wide, and 1500 miles high. A perfect cubic city which is as large as a continent. Thus it represents the Holy of Holies (which was also a cube), and is also the eternal dwelling place of God and of the Lamb.
3. It is a supernatural city which has been prepared by God for His saints. It is their eternal home and has mansions for all the saints. Their eternal imperishable inheritance is also in that city.
4. It has a wall with twelve foundations, therefore the city itself has twelve foundations, and the materials used in its construction are precious metals and precious stones (no doubt far better than anything seen on earth).
5. This city will descend from Heaven and remain as a celestial body over the earth, since the light of the New Jerusalem will give light to the earth and its nations.
6. Redeemed and restored Israel will be on earth eternally, and surrounded by saved nations.
You will find all of this in the Bible, but you will not find these things as "parables". Parables had a limited use and a limited application and it was primarily to hide spiritual truths from Christ's enemies. The Bible has a very small component of parables so I do not see how you and others start replacing prophecies with parables.
