Existentialist philosopher Søren Kierkegaard talks about the concept Leap of Faith in his work Concluding Unscientific Postscript. To walk by Faith is to trust that the ground will support your steps on this journey. There will be no empirical evidence support this claim. No money back guarantee or 1800 number to complain to when it does not work.
The highest and most beautiful things in life are not to be heard about, nor read about, nor seen but, if one will, are to be lived. – Søren Kierkegaard
