Build a small table out of a piece of wood approximately 8 inches by 4 inches. Drill four holes in each corner, and insert wooden dowels cut about 3 inches long as legs for the table. Be sure that the holes are drilled straight so that the legs are straight and the object lesson will work properly. Glue three of the legs into the table. Leave the fourth leg unglued, and use a magic marker to put a small mark on this leg so that you will know which leg has not been glued. You may want to loosen this leg slightly by inserting it and removing it from the hole a few times or by lightly sanding the dowel.
Explain that each of the legs of the table represent the principles and ordinances of the gospel – faith, repentance, baptism, and the gift of the Holy Ghost. Explain that all four legs, or principles and ordinances of the gospel, are necessary to keep the table strong and sturdy, and to keep our lives strong and sturdy. By removing just one leg, or just one principle or ordinance of the gospel, the table will fall. It is important that we keep each of these principles and ordinances in our lives so that we may be strong and sturdy like a table with all of its legs.
