Ezekiel 37:1-14 is something that if it were to happen today
more people probably would convert to Christianity.

Ezekiel 37:1-14
37 The hand of the Lord was on me, and he brought me out by the Spirit of the Lord and set me in the middle of a valley; it was full of bones.
2 He led me back and forth among them, and I saw a great many bones on the floor of the valley, bones that were very dry.
3 He asked me, “Son of man, can these bones live?”
I said, “Sovereign Lord, you alone know.”
4 Then he said to me, “Prophesy to these bones and say to them,
‘Dry bones, hear the word of the Lord!
5 This is what the Sovereign Lord says to these bones:
I will make breath[a] enter you, and you will come to life.
6 I will attach tendons to you and make flesh come upon you and cover you with skin; I will put breath in you, and you will come to life.
Then you will know that I am the Lord.’”
7 So I prophesied as I was commanded. And as I was prophesying,
there was a noise, a rattling sound, and the bones came together, bone to bone. 8 I looked, and tendons and flesh appeared on them and skin covered them,
but there was no breath in them.
9 Then he said to me, “Prophesy to the breath;
prophesy, son of man, and say to it,
‘This is what the Sovereign Lord says:
Come, breath, from the four winds and breathe into these slain,
that they may live.’”
10 So I prophesied as he commanded me,
and breath entered them; they came to life and stood up on their feet
—a vast army.
11 Then he said to me: “Son of man, these bones are the people of Israel.
They say, ‘Our bones are dried up and our hope is gone; we are cut off.’
12 Therefore prophesy and say to them: ‘This is what the Sovereign Lord says: My people, I am going to open your graves and bring you up from them;
I will bring you back to the land of Israel.
13 Then you, my people, will know that I am the Lord, when I open your graves and bring you up from them.
14 I will put my Spirit in you and you will live,
and I will settle you in your own land.
Then you will know that I the Lord have spoken, and I have done it,
declares the Lord.’”
