Dry Bones and our Role to revive them

Picture a valley filled with dry bones with the flesh rotted off after scavengers and the sun and insects and micro organisms have eaten the rest of the flesh off of them. The bones are bleached white from the hot sun and have laid lifeless after the battle that killed them for weeks or months in a pile.

In Ezekiel 37 we see God use Ezekiel to revive these bones and bring life back into them. I can't imagine witnessing this, just the image seems unbelievable to my natural mind. I want to be clear, Ezekiel was a prophet and God used him in this way to prophesy about the nation of Israel and their exile and future salvation. Our role is not the same as Ezekiel's but there is some application for us here.

Here are two parallels that we can learn from here:
1-God is sovereign over the dry bones.
And he said to me, "Son of man, can these bones live?" And I answered, "O Lord God, you know." Ezekiel's answer implies that it is God who knows if the dry bones will be revived. God is the one who controls the destiny of the dry bones in the valley.

2-God uses Ezekiel to revive the dry bones.
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.
Although none of us are prophets in the way Ezekiel was God wants us to have a role in reviving modern day dry bones. This is one of those places where its important to remember that the God who was sovereign over the dry bones in the valley is the same God who is sovereign over your salvation, your unsaved neighbor, your unsaved co-worker, your unsaved family member, or the unsaved member of your health club that you bump into regularly. That's incredible! Same God with the same power to revive, the same desire to see dry bones and dead hearts filled with life and brought to salvation in Him.

What can our role be?
