Another accomplishment of Christ's death involving the atonement is this: It gives an inheritance !
The Death of Christ, is actually the death of the testator, and it activates Covenant Blessings upon them He died for ! Heb 9:14-17
How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
15 And for this cause he is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance.
16For where a testament is, there must also of necessity be the death of the testator.
17 For a testament is of force after men are dead: otherwise it is of no strength at all while the testator liveth.
The eternal inheritance is eternal life. Its what Paul means here Gal 3:18
For if the inheritance be of the law, it is no more of promise: but God gave it to Abraham by promise
And Peter meant here 1 Pet 1:4
To an inheritance incorruptible, and undefiled, and that fadeth not away, reserved in heaven for you,
What Moses meant here Gen 17:8
And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God.
The word possession in that verse is the hebrew word achuzzah
possession by right of inheritance, Like Num 27:7
The daughters of Zelophehad speak right: thou shalt surely give them a possession of an inheritance among their father's brethren; and thou shalt cause the inheritance of their father to pass unto them
Ezk 46:16
Thus saith the Lord GOD; If the prince give a gift unto any of his sons, the inheritance thereof shall be his sons'; it shall be their possession by inheritance.
So the death of Christ bequeaths an inheritance upon them He died for ! That inheritance is inclusive of eternal life !
