No... That is the cult of fideism, and fideism only. Faith by definition is no more or less than a measure confidence in an individual or entity. It may be for a good reason or not, but it is not by definition for no reason. Other than in fideism of course... If Christ has brought me to where I am in life, and lead me each way never failing, and says he will continue to lead me until I enter His Kingdom, my faith is not irrational. I do not see the Kingdom now, but my confidence in it is well and reasonably placed.
