I say that because part of the prophecy as contained in the Psalms was that Christ would sit at the right hand of the Father in a glorified body which David does not yet have and this is why Peter mentioned David's sepulcher.
Look, I agree with you that PRIOR TO Christ's resurrection from the dead, the righteous dead were in "Abraham's bosom" or on the side of Hades which you previously mentioned, but the question which we need to ask ourselves is this:
"Has anything changed SINCE Christ's resurrection from the dead?"
From what I read in scripture, the answer to the above question is a resounding "YES!"
If not, then please begin by addressing the two portions of scripture which I've already cited you and then I'll gladly offer more verses which clearly explain that there are presently souls/spirits of the righteous dead IN HEAVEN.
I do need to take care of something for a couple of hours, but I'll check back later for your response and then respond myself accordingly.
Thanks.
Eph 1:9 Having made known unto us the mystery of his will, according to his good pleasure which he hath purposed in himself:
Eph 1:10 That in the dispensation of the fulness of times he might gather together in one all things in Christ, both which are in heaven, and which are on earth; even in him:
When is the fullness of times?
1Co 15:22 For as in Adam all die, even so in Christ shall all be made alive.
1Co 15:23 But every man in his own order: Christ the firstfruits; afterward they that are Christ's at his coming.
Notice they are made alive again? Now it is not the physical body that is resurrected...
1Co 15:35 But some man will say, How are the dead raised up? and with what body do they come?
1Co 15:36 Thou fool, that which thou sowest is not quickened, except it die:
1Co 15:37 And that which thou sowest,
thou sowest not that body that shall be, but bare grain, it may chance of wheat, or of some other grain:
1Co 15:38
But God giveth it a body as it hath pleased him, and to every seed his own body.
Now Paul goes on to give an analogy showing that the spiritual body that is resurrected is not the same as the body that is buried...
1Co 15:39 All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes, and another of birds.
Just as flesh is different, so is the spirit body...
1Co 15:40 There are also celestial bodies, and bodies terrestrial: but the glory of the celestial is one, and the glory of the terrestrial is another.
1Co 15:42 So also is the resurrection of the dead. It is sown in corruption; it is raised in incorruption:
1Co 15:43 It is sown in dishonour; it is raised in glory: it is sown in weakness; it is raised in power:
1Co 15:44 It is sown a natural body; it is raised a spiritual body. There is a natural body, and there is a spiritual body.
There are no scriptures that talk about a bodily resurrection to reunite the physical body with a spirit body. That is simply an extension of the false doctrine of the immortality of the soul. First recorded lie..
Gen 3:4 And the serpent said unto the woman, Ye shall not surely die:
God says the soul can die...
Eze 18:4 Behold, all souls are mine; as the soul of the father, so also the soul of the son is mine: the soul that sinneth, it shall die.
Eze 18:20 The soul that sinneth, it shall die. The son shall not bear the iniquity of the father, neither shall the father bear the iniquity of the son: the righteousness of the righteous shall be upon him, and the wickedness of the wicked shall be upon him.
