Lyric discussion by timekeeper 

40 years in the desert is about the isrealites going across the desert it fits because it's comparing his and the isrealites expirences and saying God taught them both stuff (least I take it in that way)......and also maybe more theologically they they meant it. The isrealights were gods chosen people and were carrying forth his plan by crossing the desert to reach the promised land, J+M were crossing the desert for Jesus to be born in beth (and fufill the prophets) so they were also carrying forth God's plan
