This picture is part of the isle of Patmos, where John wrote the book of Revelation.
I am now teaching the 21st chapter of Revelation in my End Times class, and the teaching is absolutely stunning. THE NEW EARTH WILL HAVE NO MORE SEA! In a world that is dominated by water (almost 75% of our earth is covered in ocean/sea water), this is hard for us to put into perspective. Will we then be in a world with no need for the hydrological cycles of the water/cloud/rain, river sequence? It boggles the mind...
It is one of seven "evils" that the writer John says will no longer be in existence. The rest fo the list follows in the fourth verse:
No more:
1. sea
2. death
3. mourning
4. weeping
5. pain
6. curse
7. night
