Eze. 37:7 in context speaks of the "Valley of Dry Bones", as a prophecy of Israel returning back to the land God had given them. Not as two separate nations like before but one whole and united nation.
Current preachers and evangelist have used it as an illustration of a dead lost man being breathed with new life. And rightly so used. Also many churches that have gone through a great lose in membership have received strenght from these verses with hope of risen again and being used by God.
Here I would like to bring out another biblical truth from these verses. In the Lord's dealings with us He has one goal in mind. To make us as Christ-like as can be. This goes for individuals, churches and ministries. In doing so we are striped of our carnal nature or "flesh". As little or as much as we will let Him.
During this process the Lord can and will us individuals, churches or ministries as He can and as we make ourselves available. It is when we are striped of all flesh and lie in a pile of dry bones that the Lord can do something great with us. Watching CSI on TV I've learned something interesting. When bones are dry to the point of being bleached like verse 2 says "very dry", all traces of the person is gone even the all important DNA.
Jesus is recorded in John 12:24 as saying, "Verily, verily, I say unto you. Except a corn of wheat fall into the ground and die, it abideth alone: but if it die, it bringeth forth much fruit." When we die to our selves with our dreams, passions, goals and destinies, then the Lord can stand us up. Put us together. Give us new strength and flesh. and most of all breathe His breath into us to make us a mighty army for His service.
So if you find yourselves or church/ministry "Very Dry" to the point of hopelessness, submit to His dealings and put-away yourself. Making yourself available to His makings. And there will be a "Great Shaking".
