The Abrahamic et al covenants are testamentary promises and bequests under a set of covers called the Old Testament.
This is false. If it were true then we have no promise made to Abraham's seed, who are heirs according to the promise contained in the Abrahamic Covenant:
Galatians 3
29 And if you are Christ's, then you are Abraham's seed
and heirs according to the promise.
It's the promise made to Abraham in the Abrahamic Covenant that is being referred to, that you say has been replaced.
If what you say were true,
then it would not matter whose seed we are, and we would not be heirs according to the promise made to Abraham.
@covenantee The first testament below is talking about the Mosaic Covenant of Law only:
13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh:
14 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.
16
For 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.
18
Whereupon neither the first testament was dedicated without blood.
But praise God, we are heirs of the promise contained in the everlasting Abrahamic Covenant, and because God swore
by oath when He made the promise to Abraham, we have strong consolation:
Hebrews 15
16 For men truly swear by the greater, and an oath for confirmation is to them an end of all strife.
17 In this way
desiring to declare more fully to the heirs of promise the immutability of His counsel, God interposed by an oath,
18
so that by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us,
19
which hope we have as an anchor of the soul, both sure and steadfast, and which enters into that within the veil,
20
where the Forerunner has entered for us, even Jesus, having become a high priest forever after the order of Melchizedek.
Without the everlasting covenant to Abraham it
would not even matter that Jesus is the promised seed of Abraham through whom all nations of the earth are blessed, and it would not even matter that God promised king David that his throne would remain in one of his descendants forever.
That promise to king David is also based on the everlasting Abrahamic Covenant.
You are indeed making an error by failing to know the distinction between a covenant and a will.
The Old Testament = the Mosaic Covenant/covenant of law. No other covenant.
A New Testament completely replaces an old testament and all of its promises and bequests under the principles of operation of wills and testaments. This is seen in the first clause of your own will and testament, and dates back to jurisprudence established in ancient Biblical times.
Christ is the complete fulfillment and replacement of all old testament promises and bequests. 2 Corinthians 1:20
