The doctrine of man as a mastery ladder — man as creature of dust and breath, the image of God, the image defaced and renewed in Christ, male and female, the constitution of body and soul, the origin of the soul, the covenant of works and original state, federal headship, human dignity, and death and the destiny of man. 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.
