Dava Sobel's award-winning book Longitude describes a problem faced by early sailors. The sailors could readily determine their latitude north or south of the equator by the length of the day or height of the sun. Calculating east/west longitude, however, remained very complex as well as unreliable until English clockmaker John Harrison invented the marine chronometer. A chronometer is a device that carries the real time from the home port . . . to any remote corner of the world, thus allowing sailors to determine longitude.

Like the mariners of old, we certainly need a constant guide to assist us in finding our way through life. This is exactly what happens when we seek the Lord each day with an open heart and willing spirit.
