First, we do not believe in a 'works-less faith,' but in a works-less **justification**. "It is faith alone that justifes; but the faith that justifes is never alone."
Second, "without faith it is impossible to please God." That is the 'vertical' element.
Third, we do believe in common grace--that is the 'horizontal' element.
I would highly recommend, before criticizing Reformed theology, that you be sure you understand it--and can articulate it in a way that its adherents would agree with. Look to the Three Forms of Unity, for example, or to the Westminster Standards.
