IN Christian Science practice, demonstration is paramount. It is not sufficient to say we believe the teachings of Jesus and of Mary Baker Eddy: we need to demonstrate the truth of those teachings before they can be of practical benefit to us. Our beloved Master said, "Be ye therefore perfect, even as your Father which is in heaven is perfect;" and since to be perfect is to possess all that is good and desirable, including perfect health and morals, this perfection must likewise exclude all that is evil and undesirable, such as sickness, sin and its fruits, including death.
The demonstration of perfection is our necessity, and failure to manifest perfection always calls for a higher, and ever higher, expression of goodness than the present state of mortal thought and living. "Behold, the kingdom of God is within you," was Christ Jesus' explanation of that inner impulse that continually prompts mankind to a better expression of perfect Mind. And it is solely through the practice and demonstration of Christian Science that men may find, express, and enjoy the kingdom of heaven of which the Master spoke.
The opportunity for practice is available to everyone to the extent of his knowledge of the truth about God; and it is because this opportunity meets a common need that the subject of practice is of such general interest. There is no mystery about Christian Science practice. It may be begun, and indeed is begun, with even the slightest understanding of absolute Truth. And it is by employing the power of Truth that we overcome error.
