There was once a very successful business man who sat reflecting on his memories of being raised as a farm boy. It was his chore to go to the barn in the dark to secure the farm animals before the family bedtime. He dreaded what lurked in the shadows on the way to the distant barn. His father gave him unforgettable advice.
The lantern from the farmhouse would cast its light to the yard gate and no further. When he came to the yard gate, the lantern cast its light to the corral fence and no further. When he came to the corral fence, the lantern cast its light to the windmill and no further. When he came to the windmill, the lantern cast its light to the barn door.
The wise father reminded the frightened lad that he had only to go as far as the light took him, with the assurance that the light would take him further at the next point of need. That is all we must do we just let the light lead us to the next point of need. Never are we to walk out of the light but always walk in the light. Notice that darkness flees from light and that the light always reveals what the darkness has hidden. The light always sets free what the darkness has imprisoned. The light is a key that opens the door of truth and lies must flee from truth.
