1 Corinthians 15 (WEB):we are joint heirs with Christ Jesus and we get what He got which is our physical bodies resurrected and glorified and untouchable by death just like the Lord Jesus has right now.
You are misunderstanding the point the scripture makes about a spiritual body
A spiritual body for man is a physical body that has been glorified, like Jesus has.
Jesus has a spiritual body right now seats at the Right Hand of the Father which is His same physical Body that has been glorified and He still has the scars in His hands and in His side.
(37) That which you sow, you don’t sow the body that will be, but a bare grain, maybe of wheat, or of some other kind.
(38) But God gives it a body even as it pleased him, and to each seed a body of its own.
(44) It is sown a natural body; it is raised a spiritual body. There is a natural body and there is also a spiritual body.
1 Corinthians 15:46-49 (ASV):
(46) Howbeit that is not first which is spiritual, but that which is natural; then that which is spiritual.
(47) The first man is of the earth, earthy: the second man is of heaven.
(48) As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly.
(49) And as we have borne the image of the earthy, we shall also bear the image of the heavenly.
