Thanks I would add or offer.
A promise as a covenant. A promise by himself
to himself. Faith as the power of God
to the same faith. Christ the author and finisher of our new faith.. not depending on seeds flesh of Abraham . . what the eyes see the temporal
Galatians 3:16 Now to
Abraham and
his seed were the promises made. He saith not, And to
seeds, as of
many; but as of
one, And to
thy seed, which is
Christ.
Hebrews 6:13 For when God made promise
to Abraham, because he could swear by no greater, he sware by himself,
Not a covenant because of the
flesh of
Abraham. it has
no power to offer.
I would think what some call the covenant of Abraham is an extension of the promise spoken of in the garden
Genesis 3:15. . the father striking the Son of man bruising his heel crushing the head of the serpent. It was again prophesied in Isaiah 53 establishing the government of peace that had become corrupted.
The promised demonstration began In the garden of Gethsemane the beginning of the promised three days and nights promised demonstration . . . . the father not seen working with the Son of man Jesus seen.
The father putting to sleep the apostles three times. . . Jesus suffering unto death desired they wake up again and again looking for strength . . the father continuing to refuse. . Again establishing the promise of two prophecies of two working as one. .Then they moved on to the second part of that demonstration the hill the bloody demonstration the cross. And finally the Tomb.. The demonstration of faith.
It would seem that covenants are made into what some call "dispensations" (time periods) making what they call Abrahamic promise first.
.I would think the gospel is the covenant of covenants . God works in us by a labor of His love or work of faith outside of time. Not subject to time but rather empowered by his faithful Love.
