Those watching the effect of Christian Science upon human consciousness are often struck by the increased mental activity that takes place. This is understandable to one who realizes that Science reveals spiritual man, God's likeness, who is the embodiment of omniactive Principle, divine Love. The more fully one demonstrates his true manhood as the expression of Principle, the more active he becomes. He even learns to find rest in action instead of in idleness.
There is no time for idleness in this scientific age we are entering, in which human thought is being actuated in many directions and released from various moral as well as material inertias that marked preceding eras. There is work to do, work vastly significant to the Christian Scientist, for he knows that evil claims to be likewise actuated in resisting the moral and spiritual development that underlies the world's advance out of bondage to matter. The Scientist knows that he has in Science exactly what is needed to destroy resistance to developing spirituality and thus to help humanity demonstrate the freedom of life in Spirit. He has glimpsed God's infinitely active kingdom, which is within the real man, and has felt the healing effect of the divine energies which constitute God's offspring.
The thirteenth chapter of Matthew records several of the parables by which Christ Jesus taught his followers the facts of the kingdom of heaven. The first four parables deal with tiny things, such as seeds and a little leaven, and they point to the vitality of good, which develops in the receptive human thought from the least understanding until heaven fully possesses one.
