That which is not understood often takes on an air of mystery; anything beyond the ken of mortal, material thinking appears uncertain and obscure. The Apostle Paul speaks of the mystery of godliness; and when Jesus was questioned by his disciples, "Why speakest thou unto them in parables?" (Matt. 13:10) we read that "he answered and said unto them, Because it is given unto you to know the mysteries of the kingdom of heaven, but to them it is not given."
A study of the Gospels bears testimony to the fact that Jesus had a great deal to say to the disciples about the kingdom of God. A very substantial number of his similitudes and parables were recited that he might convey to them the true and spiritual nature of this kingdom. When pressed by the Pharisees as to when the kingdom of God should come, he replied (Moffatt's translation, Luke 17: 20, 21), "The Reign of God is not coming as you hope to catch sight of it; no one will say, 'Here it is' or 'There it is,' for the Reign of God is now in your midst." The Master taught and commanded his disciples to preach that this kingdom of God is at hand, implying that it is a divine idea to be spiritually discerned in individual consciousness here and now, and not in a vague far-distant future.
Christian Science, being in strict accord with the teachings of Christ Jesus, is again bringing the comforting assurance that, regardless of the testimony of material sense, the kingdom of God, the reign of harmony and peace, is ever-present true being and that its realization is a present possibility.
