The Bible contains many prophecies that have been fulfilled in the past. It contains many that will be fulfilled in the future. But there is one which is in the process of fulfillment right now.
The hand of the LORD was upon me, and he brought me out in the Spirit of the LORD and set me down in the middle of the valley; it was full of bones. And he led me around among them, and behold, there were very many on the surface of the valley, and behold, they were very dry. And he said to me, “Son of man, can these bones live?”
And I answered, “O Lord GOD, you know.”
Then he said to me, “Prophesy over these bones, and say to them, O dry bones, hear the word of the LORD. Thus says the Lord GOD to these bones: Behold, I will cause breath to enter you, and you shall live.And I will lay sinews upon you, and will cause flesh to come upon you, and cover you with skin, and put breath in you, and you shall live, and you shall know that I am the LORD.” (Ezekiel 37:1-6)
