Ezekiel 47:8

‘Then he said to me, “These waters issue forth towards the eastern region and will go down into the Arabah, and they will go towards the sea. Into the sea will the waters go which were made to issue forth, and the waters will be healed.” '

The eastern region and the slopes down into the Arabah (the Jordan rift valley) rarely saw water. They were dry and arid and barren, apart from the occasional oasis. But even more arid was the area around the Dead Sea. Yet the point is that God can water the barren places, and instantaneously make them fruitful. And then follows the most wonderful illustration of all. The Dead Sea, that sea saturated with salt, in which nothing could live, would itself become a fresh water lake. Its waters would be healed. So God chose one of the deadest places on earth to illustrate how His waters would bring life to the world, and how He would prepare for His people a new Eden in a new earth out of the most impossible circumstances (Revelation 22:1).
