In actuality it does not change that persons reality. False faith just creates an illusion or a hallucination. For eaxample; An individual who is starving with no food or person in sight for the next 1000miles can believe that God is sending a person with a tray of food. This belief may create an illusion of rescue but it does not change the reality that there is no one within a thousand mile radius of his location. It does not bring anyon any closer to his location. It just provides him with a false sense of comfort. This is why true faith is in concert with reality.
Ok, I understand your example of 'false faith'. Can you give me an example of 'true faith'?
Well that is quite simple. But first of all let us clarify one thing. When we say false faith we mean belief in something that is not real. The persons faith is real but that which they believe in is not real.
You see people tend to forget that that there are two ways to arrive at faith. One can just believe because somebody tells them something without any further evidence. Or One can believe after someone tells them something plus they experience and see the evidence for themselves. Now an example of "true faith" would be the type of faith which is based on experience and evidence. For example; A child of 10 has faith that when he becomes hungry, a parent will supply him with an adequate amount of food. This is because ever since his birth, whenever he became hungry, his parents were always there to give him food. So, over the years has become aware of this fact. And now when he is hungry, he believes or has faith that his parents will feed him. Through those years these parents have proven themselves to be reliable and trustworthy. And through that reliability and trustworthiness, they have cultivated and strengthened that child's faith in them. Therefore, if anyone approaches that child and tells him that his parents will not feed him today, he will not believe them. This is because of all the years of overwhelming evidence which tells him otherwise.
Now if one were to study the Bible they will see that this is the type of faith which it advocates. God does not want a train of fools following him; therefore, he does not advocte following blindly. He asks you to hear first; then, conduct an investigation and gather your own evidence from reality. Everything that God does or everything that the Bible speaks of is based on reality. Unfortunately in the world today, this is not what has been happening. Believers are dismissing evidence and following presumptions and assumptions. They have taken the Bible out of this reality and placed it into another. This is why you have people trying to walk on water even though this reality says that it can't be done. And this is why the world is in the mess that it is currently in.
