1st Corinthians 3:16 states: "Do you not know that you are a temple of God and that the Spirit of God dwells in you?"
2nd Corinthians 5:17 states: "Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come."
Having read these things, how do you feel that they compare with the promise of Ezekiel 36:26?
Ezekiel 36:22-32: "Therefore say to the house of Israel, `Thus says the Lord GOD, "It is not for your sake, O house of Israel, that I am about to act, but for My holy name, which you have profaned among the nations where you went. "I will vindicate the holiness of My great name which has been profaned among the nations, which you have profaned in their midst. Then the nations will know that I am the LORD," declares the Lord GOD, "when I prove Myself holy among you in their sight. "For I will take you from the nations, gather you from all the lands and bring you into your own land. "Then I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your filthiness and from all your idols. "Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. "I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances. "You will live in the land that I gave to your forefathers; so you will be My people, and I will be your God. "Moreover, I will save you from all your uncleanness; and I will call for the grain and multiply it, and I will not bring a famine on you. "I will multiply the fruit of the tree and the produce of the field, so that you will not receive again the disgrace of famine among the nations. "Then you will remember your evil ways and your deeds that were not good, and you will loathe yourselves in your own sight for your iniquities and your abominations. "I am not doing this for your sake," declares the Lord GOD, "let it be known to you. Be ashamed and confounded for your ways, O house of Israel!"
The new creature that is reborn in Christ through the new birth, is given a new heart and a new spirit that they may be renewed in the image of Christ. This is the promise of the New Covenant.
