A switch of letters on a church sign might say something about the impact the current national conversation on race relations is having on local youth.Over the weekend, a 14-year-old boy admitted to rearranging letters on the marquee at Potter Temple Church, 714 Redwood Ave. The child switched a "b" and an "n" in the short message "Let your faith be bigger than your fears," which resulted in one word becoming the n-word.
