I was reminded this morning of how important we as Christians are to live as an example to those in need of salvation. 

"But the only letter of recommendation we need is you yourselves!  Your lives are a letter written written in our hearts, and everyone can read it and recognize our good work amoung you.  Clearly, you are a letter from Christ prepared by us.  It is written not with pen and ink, but with the Spirit of the living god.  It is carved not on stone, but on human hearts."  2 Cor. 3: 2-3

We are the braille for the spiritually blind.
