The New Covenant...

Hebrews 9:16-17 

 16* For where there is a testament, there must also of necessity be the death of the testator.
 17 For a testament is in force after men are dead, since it has no power at all while the testator lives.
 
A covenant is an agreement between two or more parties about things that are in their own power, or may be so, and this either with or without a mediator; this agreement takes effect at such time and in such manner as therein declared. A testament is a voluntary act and deed of a single person, duly executed and witnessed, bestowing legacies on such legatees as are described and characterized by the testator, and which can only take effect upon his death. 

Christ's covenant qualifies a sinner who was destined for eternal damnation.  A sinner who would have been lost without hope of eternity with Christ, at the point of faith is translated from death to life - John 5:24.  The old covenant was based on the law. The law made every man guilty because no one could be justified by the deeds of the law - Romans 8:28. 

When Christ came, He authored the new covenant. The new covenant is not based on ordinances, Priests, or the High Priest entering the holy of hollies.  Hebrews 9:11 says that Christ is our High Priest of good things to come.

The death of Christ on the cross sealed our position. The new covenant now seals me qualified by faith to partake eternity with Christ in heaven.  It qualified me all rights and privileges of a child of God, adopted into His family by grace through faith! What an amazing position a believer has in Christ!!!
