Perry,
The person who that wrote 1 Corinthians - Paul - had never seen or heard Jesus. Likewise, the later people responsible for the rest of the NT never saw or heard Jesus. They worked from their imagination. They were not recording literal history as we would know it. They were writing religious tales for a religious purpose.
If I could help that gentleman in that picture, it is this -- in October 2016 I too had a pot belly, weighing in at 110.5 kilos. Within 6 months I had dropped 33 kilos and I have kept it off ever since. If he wants to know the secret, tell him to contact me and I will tell him what worked for me.
If he wants to believe in resurrection, I do not deny him that hope. If that's what works for him, he must keep it. Hope precedes belief, precedes doctrine.
Paul heard voices in his head, saw flashes of light that no one else could, received all of his Gospel from internal voices, claiming that he had communicated with a dead man. Paul's vivid imagination created new meaning for baptism, created the eucharist, discovered the words spoken at the "Last Supper" without receiving it from any human. Later writers followed Paul.
Christianity comes from Paul. Jesus did not write anything.
