Genesis 27

...When Isaac was old and his eyes were dim so that he could not see...
Today's grace came in the form of a sound that I do not like because it is high pitched and hurts my ears.  The sound is that of audio-crosswalk systems.  The sound is different from intersection to intersection, and differs at an intersection depending on your direction of travel.  If you hold the bottom long enough, so I have come to learn, a voice actually tells you which way you will be travelling.
The audio-crosswalk system is a lifesaver and a unique tool for those who are blind.  It is a welcome sound amongst the chaos of unseen traffic noise.
It means more freedom, calm amidst a storm, and a logistical aid.....this is grace!
