Let us appeal to the word and see what it has to say...
The hand of the LORD was upon me, and He brought me out by the Spirit of the LORD and set me down in the middle of the valley; and it was full of bones.. He caused me to pass among them round about, and behold, there were very many on the surface of the valley; and lo, they were very dry.[Ezekiel 37:1,2] Here we see a valley of bones that were so far dead that the bones were pretty much sun-bleached. They had no hope of ever living again, if left to their fallen selves. There was no will they could exercise, no faith there to help them, either. They were helpless and hopeless.
He said to me, “Son of man, can these bones live?” And I answered, “O Lord GOD, You know.”[vs 4] Now, how could these bones live again in your schema? They have no will that they can exercise, neither is there any innate faith to save them. They were completely cut off from life.
Again 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 that you may come to life. I will put sinews on you, make flesh grow back on you, cover you with skin and put breath in you that you may come alive; and you will know that I am the LORD.’”[vss 4-6] Notice He told Exekiel to say 'hear the word of the LORD'. Wait!! Bones don't have ears to hear with! How can these dried up bones with no ears hear what Ezekiel said to them? Here is where God unilaterally moved upon them to bring them back to life. It was all of His doing, and none of theirs.
So I prophesied as I was commanded; and as I prophesied, there was a noise, and behold, a rattling; and the bones came together, bone to its bone. And I looked, and behold, sinews were on them, and flesh grew and skin covered them; but there was no breath in them. Then He said to me, “Prophesy to the breath, prophesy, son of man, and say to the breath, ‘Thus says the Lord GOD, “Come from the four winds, O breath, and breathe on these slain, that they come to life.”’” So I prophesied as He commanded me, and the breath came into them, and they came to life and stood on their feet, an exceedingly great army.[vss 7-10] This is a picture of how the gospel works. We are commanded to preach the gospel in all nations and to all ppl. Now, it is through the message God works to bring to life those who He wills to live. So, this OT vision that Ezekiel had tells us how it is God works to save His ppl from their sins.
As Jesus told those self-righteous scribes and Pharisees “Woe to you, scribes and Pharisees, hypocrites! For you are like whitewashed tombs which on the outside appear beautiful, but inside they are full of dead men’s bones and all uncleanness.[Matthew 23:27]
