The light of the body.-Literally, the lamp of the body. So in Proverbs 20:27, “The spirit of man is the candle (or ‘lamp’) of the Lord” — that which, under the name of “conscience,” the “moral sense,” the “inner man” discerns spiritual realities, distinguishes right from wrong, gives the light by which we see our way. If this is “single,” if it discerns clearly, all is well. The “whole body,” the life of the man in all its complex variety, will be illumined by that light. The connection with what precedes lies on the surface. Singleness of intention will preserve us from the snare of having a double treasure, and therefore a divided heart.
