The doctrine of God's works as a mastery ladder — creation out of nothing and the Creator-creature distinction, the triune Creator, the goodness and purpose of creation, the days of Genesis and the intramural interpretive options, creation and science, the invisible creation, and providence in its three aspects (preservation, concurrence, government), closing with providence and the problem of evil. 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.
