1 Cor. 15:37,38 2 Cor. 5:1,2
I hardly see how these verses support your view.
1 Cor 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:
38 But God giveth it a
body as it hath pleased him, and to every seed his own body.
Is a seed material? Does it have a physical body? Yes. Now, once a seed springs up it is not the same body, but it is still a materal, physical body.
2 Cor 5:1 For we know that if our
earthly house of this tabernacle were dissolved, we have a building of God,
an house not made with hands, eternal in the heavens.
2 For in this we groan, earnestly desiring to be
clothed upon with our house which is from heaven:
Is a house material? Yes. This says we shall be "clothed upon with our house". We shall not be a spirit without a body, we shall have a material body.
That said, this is a spiritual body and can perform supernatural acts.
Luke 24:30 And it came to pass, as he sat at meat with them,
he took bread, and blessed it, and brake, and gave to them.
31 And their eyes were opened, and they knew him;
and he vanished out of their sight.
Jesus had a real material body here, he took bread and broke it, and handed it to these disciples. But he could do the supernatural, he vanished out of their sight.
Jn 20:26 And after eight days again his disciples were within, and Thomas with them: then came Jesus,
the doors being shut, and stood in the midst, and said, Peace be unto you.
27 Then saith he to Thomas, Reach hither thy finger, and behold my hands; and reach hither thy hand, and thrust it into my side: and be not faithless, but believing.
The doors were shut, so apparently Jesus simply appeared among the disciples. But he invited Thomas to touch and handle him, so he had a material body.
Luke 24:39 Behold my hands and my feet, that it is I myself: handle me, and see;
for a spirit hath not flesh and bones, as ye see me have.
40 And when he had thus spoken, he shewed them his hands and his feet.
41 And while they yet believed not for joy, and wondered, he said unto them, Have ye here any meat?
42 And they gave him a piece of a broiled fish, and of an honeycomb.
43 And he took it, and did eat before them.
Here, Jesus plainly declares he is not a spirit, asks for meat, and eats food before them.
We will have the same kind of body Jesus has when we are resurrected.
