To dismiss something as false before having ever given serious thought to whether it might be true is merely a bias. It is not because it cannot be proven true if anyone actually used their brains. It is because people are too lazy minded to make any real effort with their brains.
Faith is not by nature or by definition blind. Blind faith is when you accept something as truth without ever having actually tested it. I believe and have faith because I have not just had teachers, I have done much searching of my own.
"Love is patient, love is kind, never jealous, never boastful, never proud, never rude. Love is not selfish or quick to anger. Love does not account a wrong suffered. Love rejoices in truth, not in evil. Love bears all things, believes all things, hopes all things. Love never fails!" the Apostle Paul
