Paul’s next reference to heaven is 1 Cor 8:5, and it speaks of false gods whether in heaven or on earth, and it doesn’t do much for this discussion. But 1 Cor 15:47 does:
42 So it is with the resurrection of the dead. What is sown is perishable, what is raised is imperishable. 43 It is sown in dishonor, it is raised in glory. It is sown in weakness, it is raised in power. 44 It is sown a physical body, it is raised a spiritual body. If there is a physical body, there is also a spiritual body. 45 Thus it is written, ?The first man, Adam, became a living being?; the last Adam became a life-giving spirit. 46 But it is not the spiritual that is first, but the physical, and then the spiritual. 47 The first man was from the earth, a man of dust; the second man is from heaven. 48 As was the man of dust, so are those who are of the dust; and as is the man of heaven, so are those who are of heaven. 49 Just as we have borne the image of the man of dust, we will also bear the image of the man of heaven.
Here we are talking about the present body and the future body.
And Paul says the present body is:
perishable, dishonorable, weak, physical, living being, earth, dust
And the future body is:
imperishable, glory, power, spiritual, life-given spirit, from heaven, of heaven.
Thus, heaven fits in with these other terms as the kind of life the believer will have after the resurrection. Paul does not say this stuff will take place in heaven, he says it is from heaven and of the heavens. It will be the kingdom of God (15:50). We will be remade for a different order. Heavenly bodies are designed for that order.
