Introduction to 'saved through childbearing' (1 Tim 2:15): the most difficult verse

Mike acknowledges 1 Tim 2:15 is the most difficult verse in the passage and possibly one of the hardest in Paul's letters. He will present five views: (1) Saved from physical death during childbirth; (2) Saved spiritually in spite of the pain of childbirth; (3) Saved spiritually by having children; (4) Saved spiritually through proper female roles (Moo's view); (5) Saved spiritually through the Messiah (Mike's preferred view). He emphasizes that this difficult verse should not be used to overturn the clearer teaching of verses 11-14. Key interpretive questions: What does 'saved' (sozo) mean? What does 'through' (dia) mean? What does 'childbearing' (teknogonia) mean? Why does it shift from 'she' to 'they'?
