Paul, in this chapter of his Letter to the Corinthians, takes up the
doubts of those who say there is no way the dead might rise again.
People ask what kind of body they might have.
To this objection Paul opposes the way things are in nature. The seed
that is to become a watermelon is nothing like the grown melon,
or where the oak tree is so different from he acorn.
Jesus said, "Eye has not seen, nor ear heard what God has planned
for those who love him. "
