What will it be like, this life after death thing? What will we look like, where will we be, of what will our existence consist? If living forever is the desired end result produced by our faith, its really reasonable to ask what that life will be like. Surely we wouldn’t want to do this if we were going to be miserable later on, forever.
Apparently the Corinthians were not only questioning the notion of a resurrection and eternal life, they were asking about what it would be like, specifically what would their body be like. They could see that people die, are buried and that buried bodies rot away, so if the body is gone, and we are to live forever, how the heck does that work.
