The New Covenant.

        "But this is the covenant which I will make with the house of Israel after those days," declares the Lord, "I will put My law within them and on their heart I will write it; and I will be their God, and they shall be my people.
                                        Jeremiah 31:33 NASB

     "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 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.
                             Ezekiel 36:25-28 NASB

    " 'Then you will no that I am the Lord, when I have opened your graves and caused you to come up out of your graves, My people. I will put My Spirit within you and you will come to life, and I will place you on your own land. Then you will know that I, the Lord have spoken and done it," declares the Lord' "
                                 Ezekiel 37:13-14NASB

     However you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. But if anyone does not have the Spirit of Christ, he does not belong to Him. If Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness. But if the spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who dwells in you. So then brethren, we are under obligation, not to the flesh, to live according to the flesh--  for if you are living according to the flesh, you must die; but if by the Spirit you are putting to death the deeds of the body, you will live. For all who are being led by the Spirit of God, these are the sons of God.
                                             Romans 8:9-14 NASB

     Do you not know that you are a temple of God and that the Spirit of God dwells in you?
                                       1 Corinthians 3:16NASB

     Or what agreement has the temple of God with idols? For we are the temple of living God; just as God said, "I will dwell in them and walk among them; and I will be their God, and they shall be my people. Therefore, come out from among their midst and be separate," says the Lord. "And do not touch what is unclean; and I will be a father to you, and you shall be sons and daughters to me," says the Lord Almighty.
                                  2 Corinthians 6:16-18 NASB

     Christ redeemed us from the curse of the law, having become a curse for us- for it is written "cursed is everyone who hangs on a tree" - in order that in Christ Jesus the blessing of Abraham might come to the gentiles, so that we would receive the promise of the Spirit through faith.
                                     Galatians 3:13-14 NASB

     God required perfect obedience to the law under the old covenant. While the law is good, yet it could not empower anyone to obey it.
     Now under the new covenant we have the law of God written upon our hearts. It is something that we want to do. God has removed the heart of stone, our stubborn wills have been subdued by the washing of regeneration in the power of the Holy Spirit.
     Under the old covenant the presence of God dwelt in the temple, in the holy of holies, symbolized by the ark of the covenant. Worshippers approached God through a system of offerings and sacrifices, with a priest as an intermediary. It was only once a year that a priest could enter the holy of holies with a sacrificial offering.
     Now we are the temples of the living God, He dwells in us by His Spirit. We enter into His presence through Jesus Christ.
     The Holy Spirit came upon certain old testament saints at specific times for specific purposes. Now in this age of grace we can enjoy His presence and power for sanctification and service at all times.
     All this is made possible to us through Christ Jesus. The broken fellowship has been restored. We enjoy sonship as God's children. God is our God and we are His people. We  have access  to the throne of grace that was not available under the old covenant, we have new changed hearts, power to live a holy life. We worship in spirit and truth, enjoying intimacy with a God who was once unapproachable because of our sin.
     Thanks be to God, through Jesus Christ!
