Belief in the existence of God is inherent in the essence of humanFrom the very time when a person’s childhood period ends and he reaches the limit of distinguishing good from bad, if he turns to his conscience, he can notice that, undoubtedly, he likes truthfulness, justice, love for one’s neighbor, service to people and other good qualities. This means that he is aware of the positive aspects of such qualities and he does not need to learn these qualities. If he is asked: - How and on what grounds did you understand that truthfulness is a good thing? He will say in response: - I understood this not from evidence and arguments, I felt it with my soul and my essence! Belief in the existence of God (the Creator of the world and all beings) is equivalent to the spiritual awareness of Him by man. To realize this, a person does not need to study and read books, because he can realize this by turning to his conscience, to understand that this world of being has its own wise and almighty Creator. Therefore, turning to the history of mankind, one can clearly see that faith in God in man has existed in all periods of the history of mankind, even in the period of its semi-savage existence. Of course, sometimes in recognizing God, a person has encountered errors. For example, man considered the sun, stars and many animals to be his gods, nevertheless, the very principle of faith in God lived in him. Now that the concept of faith in God has been clarified, some important points should be noted. Some mental factors sometimes, as a result of special conditions and causes, are consigned to oblivion. For example, if a dense material is thrown over a lamp, it will prevent light from seeping through. The same thing happens with the God-given essence of a person, that is, as a result of immersion in sensual desires and passions, the divine essence of a person remains covered and inaccessible and alienates a person from Allah to such an extent that it seems to him that such a God-given essence does not exist at all. If this veil leaves, then the person very soon and by himself realizes his divine essence in himself. People who have distanced themselves from their divine essence, as a result of wallowing in sins and sensual lusts, at the moment of danger, for example, at the moment of danger in an airplane or in a car, seeing that they will not be able to escape in any way, resort to asking for the mercy and help of the Lord, that is, at this moment in them, in the most correct form, a sense of knowledge and admiration for the Lord awakens. The sixth immaculate Imam of the Shiites, His Grace Imam Sadiq (peace be upon him) in a very concise form deals with this issue. Someone asked his lordship to orient him to God and the Creator of the worlds (that is, to give him an argument for the existence of God). His Lordship said, "Have you sailed on a ship?" -Yes. -Has such an event happened to you that your ship was wrecked and there would be no other ship nearby to tackle you, and you would not know how to swim in order to save your life (that is, so that you would be deprived from all sides opportunities to get help?) -Yes. - At the moment when you lost your last hope of getting help and salvation, did not the consciousness arise in the depths of your soul that someone could equip you? - Why, in my soul I felt that there is a force that can save me from inevitable death! His Grace Imam Sadiq said: -The power that you realized at that moment is that very God. That is, the very one whom, at a moment of fear and helplessness, a person can willy-nilly notice, the same force that moves a person in His direction, when the veil of self-greatness, selfishness, hope in people and worldly life moves aside - is God, the Creator worlds, Eliminator of all needs and Savior of all those in distress.
