It is time we recognized that belief is not a private matter; it has never been merely private. In fact, beliefs are scarcely more private than actions are, for every belief is a fount of action in potentia.

A belief is a lever that, once pulled, moves almost everything in a person’s life. Are you a scientist? A liberal? A racist? These are merely species of belief in action. Your beliefs define your vision of the world; they dictate your behavior; they determine your emotional responses to other human beings. If you doubt this, consider how your experience would suddenly change if you came to believe one of the following propositions:

1. You have only two weeks to live.
2. You've just won the lottery prize of one hundred million dollars.
3. Aliens have implanted a receiver in your skull and are manipulating your thoughts.

These are mere words- until you believe them. once believed, they become part of the very apparatus of your mind, determining your desires, fears, expectations, and subsequent behavior.

Belief, that sacred faculty which prompts the decisions of our will, and knits into harmonious working all the compacted energies of our being, is ours not for ourselves but for humanity. It is rightly used on truths which have been established by long experience and waiting toil, and which have stood in the fierce light of free and fearless questioning. Then it helps to bind men together, and to strengthen and direct their common action. It is desecrated when given to unproved and unquestioned statements, for the solace and private pleasure of the believer; to add a tinsel splendour to the plain straight road of our life and display a bright mirage beyond it; or even to drown the common sorrows of our kind by a self-deception which allows them not only to cast down, but also to degrade us. Whoso would deserve well of his fellows in this matter will guard the purity of his beliefs with a very fanaticism of jealous care, lest at any time it should rest on an unworthy object, and catch a stain which can never be wiped away. It is not only the leader of men, statesmen, philosopher, or poet, that owes this bounden duty to mankind. Every rustic who delivers in the village alehouse his slow, infrequent sentences, may help to kill or keep alive the fatal superstitions which clog his race. Every hard-worked wife of an artisan may transmit to her children beliefs which shall knit society together, or rend it in pieces. No simplicity of mind, no obscurity of station, can escape the universal duty of questioning all that we believe. It is true that this duty is a hard one, and the doubt which comes out of it is often a very bitter thing. It leaves us bare and powerless where we thought that we were safe and strong. To know all about anything is to know how to deal with it under all circumstances. We feel much happier and more secure when we think we know precisely what to do, no matter what happens, than when we have lost our way and do not know where to turn. And if we have supposed ourselves to know all about anything, and to be capable of doing what is fit in regard to it, we naturally do not like to find that we are really ignorant and powerless, that we have to begin again at the beginning, and try to learn what the thing is and how it is to be dealt with — if indeed anything can be learnt about it. It is the sense of power attached to a sense of knowledge that makes men desirous of believing, and afraid of doubting.

It is not so much what you believe in that matters, as the way in which you believe it and proceed to translate that belief into action.

Belief’s always right.. It’s all right and it’s also unmistakable. Every man has somewhere about him some belief for which he’d die. Only isn’t it improbable that your parents and guardians told it to you? If there is one won’t it be part of your own flesh and spirit?

No man holding a strong belief on one side of a question, or even wishing to hold a belief on one side, can investigate it with such fairness and completeness as if he were really in doubt and unbiased; so that the existence of a belief not founded on fair inquiry unfits a man for the performance of this necessary duty. Nor is it that truly a belief at all which has not some influence upon the actions of him who holds it. He who truly believes that which prompts him to an action has looked upon the action to lust after it, he has committed it already in his heart. If a belief is not realized immediately in open deeds, it is stored up for the guidance of the future. It goes to make a part of that aggregate of beliefs which is the link between sensation and action at every moment of all our lives, and which is so organized and compacted together that no part of it can be isolated from the rest, but every new addition modifies the structure of the whole. No real belief, however trifling and fragmentary it may seem, is ever truly insignificant; it prepares us to receive more of its like, confirms those which resembled it before, and weakens others; and so gradually it lays a stealthy train in our inmost thoughts, which may someday explode into overt action, and leave its stamp upon our character for ever.

To believe is to become what you believe

Every man has somewhere about him some belief for which he'd die. Only isn't it improbable that your parents and guardians told it to you? If there is one won't it be part of your own flesh and spirit?

Belief is just like morality. People who believe something often think they are superior to others.

Belief is a moral act for which the believer is to be held responsible.

In adaptive terms, belief has been extraordinarily useful. It is, after all, by believing various propositions about the world that we predict events and consider the likely consequences of our actions. Beliefs are principles of action: whatever they may be at the level of the brain, they are processes by which our understanding (and misunderstanding) of the world is represented and made available to guide our behavior.

It is what you believe that translates in the life you live.

Why does a man refuse to believe? Because he has confidence in himself; because he has not a sense of his own sins; because he has not love in his heart to his Lord and Saviour. Unbelief men are responsible for. Unbelief is criminal because it is a moral act — an act of the whole nature. Belief or unbelief is a test of a man's whole spiritual condition, just because it is the whole being, affections, will, conscience, and all, as well as the understanding, which are concerned in it.

The belief in a thing makes it happen.
