Eleven miles off the east coast of Scotland, in the North Sea, stands the Bell Rock Lighthouse. It has endured the ferocious onslaught of the North Sea's violent storms since 1811. It rests upon less than one acre of solid rock. That small reef is covered by seawater for 20 hours of every day. The builder of the lighthouse, Robert Stevenson and his band of 65 skilled artisans, had only four hours each day to chink away the stone and gouge a foundation in the rock. As a result of this painstakingly patient work, the 115-foot-tall lighthouse is still in use today.

In a similar way, parents have a short period of time in which to build their children's lives to withstand the storms of life. Parents must take advantage of that window of opportunity and carve out a foundation for them on solid rock.
