What is the meaning of Ezekiel 37 Verse 7 and how we can apply it to our lives?

So I prophesied as I was commanded. And as I prophesied, there was a sound, and behold, a rattling, and the bones came together, bone to its bone. And I looked, and behold, there were sinews on them, and flesh had come upon them, and skin had 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 may live.'

So I prophesied as he commanded me, and the breath came into them, and they lived and stood on their feet, an exceedingly great army. Then he said to me, 'Son of man, these bones are the whole house of Israel. Behold, they say, 'Our bones are dried up, and our hope is lost; we are indeed cut off.' Therefore prophesy, and say to them, Thus says the Lord God: Behold, I will open your graves and raise you from your graves, O my people. And I will bring you into the land of Israel.'

The word of the Lord came to me: 'Son of man, take a stick and write on it, 'For Judah, and the people of Israel associated with him'; then take another stick and write on it, 'For Joseph (the stick of Ephraim) and all the house of Israel associated with him.' And join them one to another into one stick, that they may become one in your hand. And when your people say to you, 'Will you not show us what you mean by these?' say to them, Thus says the Lord God: Behold, I am about to take the stick of Joseph (that is in the hand of Ephraim) and the tribes of Israel associated with him. And I will join with it the stick of Judah, and make them one stick, that they may be one in my hand.'
