Where there exists faith there also exists a road by which the human psyche can travel upon. Progress and most actions have their grounding in faith and the awareness of that is probably not so often understood by humans in general. Most secular people put their trust in psychologist when all that they have done cant bring them what they so desperately need. They put their trust in medicines to subdue the feelings that in a lot of cases actually are trying to tell them something.
The placebo effect is scientific relevant because it is empiric and positive with sometimes equal effects of medicine. So is the generally lesser known nocebo effect which work in a more destructive way as it is effecting the human psyche and biology. So belief in the good or the harmful have real effects not thoroughly understood by modern science.
Faith serves us from a pure psychological perspective as it can give us hope and motivate us to keep on going against all odds. Faith is like the carrot on a stick hanging down in front of the stubborn donkey, it motivates the donkey to go forward. Doubt on the other hand keeps us restraint so that no movement forward is to be made. Where would mankind be without faith? We must be humble to the fact that this world have certain limitations as do we. If ones belief system solemnly is based upon the materialistic worldview that comes with certain limitations concerning the amount of hope, motivation, resilience,deliverance and comfort that one can get.
So as we move into faith within the immaterial worldview which is related to God, it transcends the limits of the material world. Therefore it can serve man immensely more. A believer in God can rely on the father as someone to take of the weight from concerns thru the practice of prayer. And in the hardships of life trust in a greater plan that God has regarding ones life, the future is unknown to the believer but faith in God gives him or her deliverance from worries and uncertainties.
One aspect people do not focus or prioritize upon as they are setting goals is if the goal is truthful or based upon belief. Often that which later becomes manifested has its origin in the thoughts of men who believe in the reality of a possibility of that idea. If belief in God is irrelevant for atheist who so to say believe in ideas themselves or relate to thought structures of dead thinkers who´s only current type of existence is thru their books,words and ideas. Why is the idea of a dead philosophizer of any real worth when they so to say do not exist? Is their word only truthful if the source of them exist? So as they claim to have no need to believe in a God that does not exist. They should ask themselves why believe in anyone that does not exist?
God speaks to us thru words written down and the words carry hope meaning, deliverance, guidance and mercy. There function upon the human psyches are real and therefore truthful. I believe that the value someones word has have to do in what way it can bring answers of existential worth and transform someone towards the highest good and be the frame and goal for the moral values progressive works. And enable men/women to withstand trends and cultural movements of different societies that directly or indirectly go against that which is good. If one believes in the potential of transforming man by the word and the truth aspect of it that truly justifies a belief in God.
John 1 King James Version (KJV)
1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 The same was in the beginning with God.
3 All things were made by him; and without him was not any thing made that was made.
4 In him was life; and the life was the light of men.
5 And the light shineth in darkness; and the darkness comprehended it not.
