The seed has no sexual reproductive capability...but the plant does.
In the gospels it was described a little differently. Perhaps the description in Revelation includes symbolism, rather than just a pretty word picture.
You mean after they get their new, reborn bodies, right?
I don't know what that means.
I don't see any evidence of the Father and the Spirit having bodies. But humans have bodies. When Jesus became a human, He also began to have a body. Jesus remains a human forever, with a body. That makes it seem like you can't be human without body.
How do you know this? What scripture talks about bodiless humans in heaven?
But the fact that we seem to need them might be informative as to why, and might suggest that your theology about the human body might be wrong.
The simile of the seed dying and being reborn is not to the extent to claim to know that the new body is reproductive. Plants reproduce asexually and sexually but we don't know if we will have wives in the afterlife, Jesus suggested not, Swedenborg had other ideas.
John the apostle in Revelation describes Jesus new body as glorious or looking not like flesh but like a gem, and the angel in the same passage, has the appearance of glowing metal. John is not merely being polite. It reminds me of a black and white picture of a model with a flower, and it looks like she is made of marble, with rippling blood vessels.
Yes, the Heavenly body will be able to stand beside God the Father...
In 1 Corinthians 6 Paul describes that doing something like perving and coveting is done in the mind, with real heart intent, but fornicating involves the loins, union ability, water weld, blood to blood, sexual union. Heaven is place with a different time nature. History is different there. You can ask God to change the past and future. You can repent and do more than change your heart desire. Angels have no history. We don't know if they have bodies, if they do they may not always use them. Like angels, our spirits and souls can exist in Heaven and God can change them as we both wish, but a body conception like a baby or even sexual intercourse will part of the history of the body forever and the body can be painted or atoned for with Jesus' sacred and powerful blood. So it is justified.
We can be human without a body. Incomplete.
Only Enoch, maybe Moses, Elijah, maybe Mother Mary, and Jesus have their bodies mentioned in Heaven. The bodies we have now will be buried or cremated, and until the resurrection, will remain on Earth. "The Earth and the Sea will give up their dead."
Ian McCormack describes his body of light in Heaven. Otherwise you think God will make a new body for you in Heaven?
