It is a deep unity, maintained by the will and deliberately strengthened by habit; reinforced by (in Christian marriages) the grace which both partners ask, and receive, from God.

C. S. LewisAll joy... emphasizes our pilgrim status; always reminds, beckons, awakens desire. Our best havings are wantings.
