As we look at Ezekiel, we see the possibility that the dry bones of Ezekiel 37 signify the regathering of Israel in 1948.
We know that Romans 10-11 and Ezekiel 38-39 both say that all Israel will be saved. But, as we look at Ezekiel 37, we see two prophetic movements. The first, during the healing wave that came after WWII, the scattered nation of Israel was regathered, and brought into one being, a body with joints, sinews, and covered with skin. But, the Word of God says they are dead. They are not born-again, they are not alive, but are dead in their trespasses and sin.
After this, God instructs Ezekiel to “prophesy again”, and that the breath of life would come into them. This could very well be the pouring out of the Spirit prophesied in Ezekiel 39, when God no longer hides His face. That would mean, another great prophetic move of God is coming upon the Earth, in fulfillment of the second prophecy of Ezekiel.
Whereas the first one resulted in the scattered, dried bones being formed again into a body, so this one, when all of Israel is born again in recognition of Jesus Christ as their Messiah, will be that much greater.
As Paul said, Israel’s restoration will be life from the dead–that is, world-wide revival.
