The doctrine of last things as a mastery ladder — the already/not-yet, death and the intermediate state, the return of Christ, the resurrection of the body, the final judgment, the millennium (amillennial, postmillennial, and premillennial views presented fairly), antichrist and apostasy, hell, and the new heavens and new earth. Each mode trains a different skill; the final exam ranges over the whole course. Unlock each subtopic by scoring at least 90% on its mastery check. Cards you grade enter spaced review: the dashboard tells you when they fall due.
