Jesus clearly faced the same challenge; he used many different images in his attempts to get the idea across to his diverse listeners. The kingdom is like a farmer sowing seeds of new possibility; it's like a housewife whose joy is great in finding a lost coin; it's like a merchant who finds a pearl of great price (all from Matthew 13).
I think the image he uses most, however, is the image of light. He wanted his listeners-as he wants us today-to find and recognize the light that is our true expression.
"I am the light of the world," he said. "Whoever follows me will never walk in darkness but will have the light of life" (John 8:12).
"You are the light of the world" (Matthew 5:14).
"The light shines in the darkness, and the darkness did not overcome it" (John 1:5).
Other writers, from Paul through Revelation, used the same image of light to describe the ineffable-the effect the teachings of Jesus Christ will have upon our life experiences. What they describe is not the opposite of darkness; it is a light that has no darkness. It is the light we truly are, shining as new possibilities, new choices.
It's not that in the light we are free from fear-based ideas, whether from collective consciousness or from our own sensory input. Rather, it's that we now know the light we are, so our choices become surer and easier.
It would seem Jesus Christ knew what he was doing when he chose to speak to us often of the light. We are the Christ, and in that Truth our kingdom lies, waiting to express through our clear, loving, and light-filled choices.
