I have no problem with parties thrown at heaven, especially for the newly raised humans. But it could also be a metaphor for realities we can not describe in human terms. What is heaven like?
1 Corinthians 15 makes it clear the Christian hope lies in the ressurection. No ressurection we - not merely our bodies - perishes. No disembodied parties. Whatever Paul believed the soul was doing in the meantime, it amounted to 'no hope' ☺️
