On having a physical relationship... with God!
If a human being was a candy bar, what would the label say? What are our ingredients? What component parts make up a human being?
Comedians, poets, and philosophers have all weighed in on the subject. For myself, I am particularly attracted to the nursery rhymes about what little boys and little girls are made of. But "sugar and spice" notwithstanding, the persistent witness of scripture seems to suggest these two primary ingredients in the human makeup: spirit and flesh. Everything else in us traces back to one of those two elements.
