Sailing puts the wind to work, acting on the sails to propel the boat along. A good navigator will avoid sailing too close to the cliffs to maintain the safety of their ship, boat etc. Those cliffs are clearly potential obstacles in the way. When the boat is sailing smoothly, the wind beneath the sails, and no obstacles- it is unknown how far you may be able to go. I like to think that we are navigators of our own lives, only in my life with out the wind of the Holy Spirit guiding me away from cliffs, through obstacles I believe that I may crash my vessel and , of course not get very far. The wind of the Holy Spirit directs us , keeps us safe and propels us to the things that we are meant to be and do.
Smooth sailing!
