Matthew 26:28 "For this is my blood of the new testament, which is shed for many for the remission of sins."The amazing, wonderful reality of the New Covenant is that God has now come to live inside man. We have access to God through Christ every second we live. As long as we breathe we can touch and know the presence of God.
Jesus will never leave us, by the Holy Spirit he is interwoven into our Spirit and Christ in all his fullness dwells within us.
We are never alone, we are never separated, the only barrier to living in the fullness of Christ is us. It is all there for us to receive and live in but it is limited by our response to his grace. God will not force himself upon us the more we enjoy, revel and depend upon his grace the more it will overflow out of our lives.
As Andrew Wommack explains the New Covenant is all about what God has done for us and made available to us.
The principle of the Old Covenant was "do" and you shall live. The principle of the New Covenant is "it is done," and includes redemption, reconciliation, righteousness, and sanctification. The work is finished! We are complete in Him!
If the Old Covenant had no defects, there would have been no attempt to institute another (Heb. 8:7). In the Old Covenant, men found themselves unable to abide in its agreement, for it was based upon a man's performance.
The new agreement, however, is based totally upon God's grace. Under the Old Covenant, men approached God through a priest, while under the New Covenant, we have direct access to the Father through Jesus Christ. Under the Old Covenant, a man's sin led to his death while under the New Covenant, God is merciful to our unrighteousness. Under the Old Covenant, man could not be cleansed of a consciousness of sin while under the New Covenant, our sins and iniquities are remembered no more, and our guilty consciences are cleansed.
Prior to salvation we are incomplete and there is a constant striving in every person to satisfy their hunger. Through the new birth we are complete in Christ and our hunger now should only be for more revelation of what we already have in Christ.
In the same way that Jesus had the fullness of God in Him, we also have the fullness of Christ in us. That makes us complete or perfect in Him, that is speaking of our spiritual man. Our born-again spirit is identical in righteousness, authority, and power to Christ's spirit, because our born-again spirit is the Spirit of Christ (Rom. 8:9). It has been sent into our hearts crying "Abba Father" (Gal. 4:6).
