Biblical verification of an atheist message

Austin has put up one of those mild, positive, and effective billboards that so rile up the faithful. It’s impressive that it’s happening in Texas, but I noticed something portentious in its placement: it’s on I-35, a road familiar to me as the major north-south artery in this region (Minnesota and Texas have a direct connection, you see). I-35 also has a freakish association in the fundagelical brain, because of a passage in Isaiah 35:8:

And an highway shall be there, and a way, and it shall be called The way of holiness; the unclean shall not pass over it; but it shall be for those: the wayfaring men, though fools, shall not err therein.

If any indignant bible-lovin’ Texans start complaining about the billboard, I suggest we tell them to read their Good Book, where it clearly says there can be no error in the sign.
