The Story Behind the Puzzle
As I pondered the wonder of salvation by grace, not by works, an idea for how to illustrate of this entered my mind. I would make a puzzle, that is seemingly impossible to unlock by one’s own effort, and yet unlocks effortlessly when placed in a different type of force field! I would make the puzzle with two interlocking pieces of wood in the shape of a cross – the well-known symbol of the Christian faith. It became my passion to the design such a puzzle, build a working model, and using it as an object lesson! Along the way I would incorporate woodworking, physics, mathematics, engineering and scripture to provide a full-bodied illustration of this central theme of the Gospel.
Behind the scenes
How The Classic Cross Puzzle is Built
The wood is milled to precise sizes and special jigs are used to ensure that all the pieces of the puzzle fit together properly. The finished parts are coated with a protective coating of polyurethane. Old- fashioned nails are added to the base to serve as a decorative holder for the colorful instruction sheet. Green felt lines the pocket of the base to hold the cross securely and adds a splash of contrasting color and texture.
