What MAD doctrine misses totally is that the promise to Abraham is the inheritance of the regenerated earth, which "establishes the heavens."
The promise is to all believers who are born again in Christ; the Jew, first, and also the Gentiles.
This is the redemption which He was, from the beginning, the "Lamb Slain from the foundation of the earth", and was to come/appear/be revealed in human flesh of the second creation, in the pre-appointed Season, to fulfill; which season is the "Day of Atonement;" which is fulfilled now, forever.
Today is the continuing "Day of Salvation" in which the One Gospel message of His Everlasting Gospel is to be offered to all men, so that all men may have the opportunity to come to the Father through the Son, to be adopted as sons of God in the Firstborn, and inherit everlasting Life, and partake in a share of the kingdom which YHWH is come to ransom and restore, for the human sons of God to fill and rule.
MAD misses so much by doting on words out of context, without connecting them to the Living Oracles by Scripture comparison, which Oracles teach us these things, as a "Tutor".
1Sa 2:8 He raiseth up the poor out of the dust, [and] lifteth up the beggar from the dunghill, to set [them] among princes, and to make them inherit the throne of glory: for the pillars of the earth [are] the LORD'S, and he hath set the world upon them.
Hannah's praise song in 1 Samuel 2, is taken right out of Enoch 1, in which book we can learn that God had already revealed the Son of Man who was "with God and who was God;" who was "hidden in God from the beginning;" who was to come; who was "to be revealed in His season;" who would be the "Light to the Gentiles" -the "Salvation of all Gentiles".
The only way to have a part in His eternal kingdom -and to be therefore seated on a "throne of glory", which seating with Him on His throne is to have a share [be made part takers] in the ransomed dominion [which dominion Adam, the former son of God, lost -Luke 3:38; Genesis 3]-
is to be born into His One Living Spirit, "Today", while we have our being intact, and
this is the call of the Church/the Bride, and the Spirit, to all men, during this time of the harvest of souls; which souls are to be ingathered "all together", in the first harvest of earth's sons, [typed in Pentecost] which is to come. "Today", while it is still "Today", which is the Church age, He calls all men to repentence and adoption into His Spirit by second birth.
MAD denies the neccessity to be born again in Spirit -which is why they will not submit their Adam flesh they wear to water baptism, either, in obedience to the Gospel of Christ.
1Sa 2:8 He raiseth up the poor out of the dust, [and] lifteth up the beggar from the dunghill, to set [them] among princes, and to make them inherit the throne of glory: for the pillars of the earth [are] the LORD'S, and he hath set the world upon them.
Isa 49:8 Thus saith the LORD, In an acceptable time have I heard thee, and in a day of salvation have I helped thee: and I will preserve thee, and give thee for a covenant of the people,
to establish the earth, to cause to inherit the desolate heritages;
The promise of the inheritance is fulfilled in the uniting of heaven and earth, when the Presense of Glory fills all things.
Romans 4 speaks of the inheritance which all the justified by faith believers in Christ's promises receive:
Abraham Justified Before Circumcision
9 Does this blessedness then
come upon the circumcised
only, or upon the uncircumcised also? For we say that faith was accounted to Abraham for righteousness.
10 How then was it accounted? While he was circumcised, or uncircumcised? Not while circumcised, but while uncircumcised.
11 And he received the sign of circumcision, a seal of the righteousness of the faith which
he had while still uncircumcised, that he might be the father of all those who believe, though they are uncircumcised, that righteousness might be imputed to them also,
12 and the father of circumcision to those who not only
are of the circumcision, but who also walk in the steps of the faith which our father Abraham
had while still uncircumcised.
The Promise Granted Through Faith
13 For the promise that he would be the heir of the world was not to Abraham or to his seed through the law, but through the righteousness of faith. 14 For if those who are of the law are heirs, faith is made void and the promise made of no effect, 15 because the law brings about wrath; for where there is no law
there is no transgression.
16 Therefore it is of faith that it might be according to grace, so that the promise might be [fn4] sure to all the seed, not only to those who are of the law, but also to those who are of the faith of Abraham, who is the father of us all 17 (as it is written, "I have made you a father of many Gentiles/Nations") in the presence of Him whom he believed--God, who gives life to the dead and calls those things which do not exist as though they did;
18 who, contrary to hope, in hope believed, so that he became the father of many Gentiles/nations.
