"Explorers in the realm of the spirit are like Columbus when he landed on a new continent and did not know what lay beyond. We probably have only just reached the beach-heads of prayer. A vast unknown continent lies beyond us to be explored, conquered and cultivated. Nothing is so thrilling as discovery. Every Christian can and should join in the highest of all adventures in the most wonderful of all worlds, the world of the spirit. Nobody need leave home nor give up his work, for he has his mind with him every minute, and it is in the mind that this exploration is carried on."
Frank C. Laubach, Prayer, page 50.
