The hand of the LORD was upon me, and he brought me out in the Spirit of the LORD and set me down in the middle of the valley; it was full of bones. And he led me around among them, and behold, there were very many on the surface of the valley, and behold, they were very dry. And he said to me, “Son of man, can these bones live?” And I answered, “O Lord GOD, you know.” 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.”
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. And you shall know that I am the LORD, when I open your graves, and raise you from your graves, O my people. And I will put my Spirit within you, and you shall live, and I will place you in your own land. Then you shall know that I am the LORD; I have spoken, and I will do it, declares the LORD.”
(Ezekiel 37:1-14 ESV)
And I will ask the Father, and he will give you another Helper, to be with you forever, even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be in you.
“I will not leave you as orphans; I will come to you. Yet a little while and the world will see me no more, but you will see me. Because I live, you also will live. In that day you will know that I am in my Father, and you in me, and I in you. Whoever has my commandments and keeps them, he it is who loves me. And he who loves me will be loved by my Father, and I will love him and manifest myself to him.” Judas (not Iscariot) said to him, “Lord, how is it that you will manifest yourself to us, and not to the world?” Jesus answered him, “If anyone loves me, he will keep my word, and my Father will love him, and we will come to him and make our home with him. Whoever does not love me does not keep my words. And the word that you hear is not mine but the Father's who sent me.
“These things I have spoken to you while I am still with you. But the Helper, the Holy Spirit, whom the Father will send in my name, he will teach you all things and bring to your remembrance all that I have said to you.
“But when the Helper comes, whom I will send to you from the Father, the Spirit of truth, who proceeds from the Father, he will bear witness about me. And you also will bear witness, because you have been with me from the beginning.
(John 14:16-26 & 15:26-27 ESV)
