That's interesting. I would take that same passage as an indication that burial is to be preferred to cremation for Christians (the bones remained and were identifiable hundreds of years later).On Cremation: Several patriarchs had their bones taken back to a land special to them. This meant the body had to be exposed to, well nature as it were, so the soft tissue was done away with. Cremation is very similar in that only the bone materials remain. I see no difference.
God will raise all the dead, no matter what's happens to their bodies.
