Faith is not blind faith; it is taking that step out knowing that where you place your foot, it will hold you. Faith is based on truth and reality; it is really knowing the truth and seeing the reality before you take the step. When you are walking with  god  there is no difference, you have to make sure you know the truth before you step out then watch it all become a reality. As GOD is real, so to the devil, there is sanity and insanity GOD is the only right so the devil is the only wrong GOD always left the choices of who you follow up to you. The further you move away from GOD, the more insanity becomes your only reality, that is why GOD made a hell for the devil not for you.
