Full context:   Luther writes: Scripture divides man into three parts, as says St Paul (1 Thess. 5:23)... And every one of these three, together with the entire man, is also divided in another way into two portions, which are there called Spirit and Flesh. Which division is not natural, but attributive; i.e. nature has three portions spirit, soul, and body... In the tabernacle fashioned by Moses there were three separate compartments. The first was called the holy of holies: here was God's dwelling place, and in it there was no light. The second was called the holy place; here stood a candle-stick with seven arms and seven lamps. The third was called the outer court; this lay under the open sky and in the full light of the sun. In this tabernacle we have a figure of the Christian man. His spirit is the holy of holies, where God dwells in the darkness of faith, where no light is; for he believes that which he neither sees nor feels nor comprehends. His soul is the holy place, with its seven lamps, that is, all manner of reason, discrimination, knowledge, and understanding of visible and bodily things. His body is the forecourt, open to all, so that men may see his works and manner of life.
