The Lord is inviting His church to see that which is desolate and shout for joy over it. Your shout of joy will make the desolate places bloom, the barren places bring forth fruit and the dark places explode with light. Your shout has power to transform anything. Remember God spoke into desolations and brought forth life and light (Genesis 1). You can do the same thing. Speaking what is does not change it, shout for joy over it and watch it blossom.
Isaiah 54:1 “Shout for joy, O barren one, you who have borne no child;
Break forth into joyful shouting and cry aloud, you who have not travailed;
For the sons of the desolate one will be more numerous Than the sons of the married woman,” says the LORD.”
When the land of Israel was barren, uninhabited and desolate someone spoke life in that land many years ago and now its the 8th wealthiest nation in the world. Shout for joy, your voice carries life and power. Shout!
