Psalm 62:8: "Trust in The Lord at all times. Pour out your heart before Him. God is a refuge for us."
A message from a friend: "Out of the fog comes a fellow traveler heading in the same direction, generally, and we journey together for awhile..."
So the cairns make me think of walking that trail and sometimes not knowing where to go or which path to take. Cairns give direction, point the way...and are a thoughtful message from someone who has traveled the path before me. It's comforting.
