I really do believe that Jesus Christ actually defeated death and that there are many witnesses to what happened that were to be found in the early Christian congregation before any of the new testaments scriptures were written at all. These scriptures mentioned what was already believed among those who had seen and heard themselves. That is very central in Christian belief as I see it.
The scriptures were not written as empty speculation but refers to things that were already believed in the existing congregation dating back to the 30:s in the first century. That is so important I think.
