Someone was walking on a narrow path. It was only as wide as the person's foot. On either side of the path demons taunted the person walking. They called out, and jeered, "The path is too narrow, you will fall off! Jump! Just jump off!" They were saying this because if the person stayed on the path they would be protected by the Lord but if they got off the path they could be attacked. The person's step was sure, there was not a hesitancy of step, but the jeering brought great fear to the person's mind. They became afraid and felt they could not continue to put one foot in front of the other to walk safely along the path.
The person jumped off the path into the brambles. It was not the person's feet that slipped, but the fear in the person's mind that caused them to doubt, and convinced them to jump off it.
Two angels, one on either side of the path, watched the person with some dismay. They wanted to help but were not able to help the person until he or she decided that they wanted to get back on the path.
Do not be lured off the narrow path by fear that you will lose your step. "Thy Word is a lamp unto my feet, and a light unto my path (Psalm 119:105). " He makes my feet like hinds (deers) feet, and sets me upon my high places. " (Psalm 18:33).
