From the church's website:

The question often asked is: 'What is its meaning?" "What did the author have in mind in creating the design?" While creating the mural Mr. Frazier kept in mind a Biblical text: "Be still and know I am God." Through design, color and symbolism he has attempted to portray the concept of the good in creation inherent from the beginning and which will continue to exist. One senses the swirl of creative forces in the universe-rugged, relentless, powerful. Interwoven in the midst of the turbulent eddies the central figure symbolizes the universal deity of all time and places.

If you say so, friends.
