It appears that the invitation of religion to a change of heart, rather than a change of belief, is founded on solid psychological laws.

I need not dwell on the way in which Divine love, as the saints have understood it, answers to the complete sublimation of our strongest natural passion; or the extent in which the highest experiences of the religious life satisfy man's instinctive craving for self-realization within a greater Reality, how he feels himself to be fed with a mysterious food, quickened by a fresh dower of life, assured of his own safety within a friendly universe, given a new objective for his energy.

It is notorious that one of the most striking things about a truly spiritual man is, that he has achieved a certain stability which others lack.

In him, the central craving of the psyche for more life and more love has reached its bourne; instead of feeding upon those secondary objects of desire which may lull our restlessness but cannot heal it He loves the thing which he ought to love, wants to do the deeds which he ought to do, and finds all aspects of his personality satisfied in one objective.

Every one has really a forced option between the costly effort to achieve this sublimation of impulse, this unification of the self on spiritual levels, and the quiet evasion of it which is really a capitulation to the animal instincts and unordered cravings of our many-levelled being.
We cannot stand still; and this steady downward pull keeps us ever in mind of all the backward-tending possibilities collectively to be thought of as sin, and explains to us why sloth, lack of spiritual energy, is held by religion to be one of the capital forms of human wrongness.
I go on to another point, which I regard as of special importance.
It must not be supposed that the life of the Spirit begins and with the sublimation of, the instinctive and emotional life; though this is indeed for it a central necessity.
