Open theological questions Mike personally still has

Mike lists two major personal areas of ongoing uncertainty: (1) Eschatology — particularly how massive portions of the Old Testament connect to the book of Revelation (describing it like a conspiracy board of interconnected threads spanning the entire OT), and (2) Once saved always saved (eternal security) — he regards this as more complicated than typically presented and says he has not resolved it to his satisfaction. He emphasizes his uncertainty is personal and does not imply others cannot have these settled.
