One Voice United in Prayer is the theme of Starke County’s National Day of Prayer observation. It will take place this morning at 7 a.m. at the community center in downtown Knox. The program will feature a concert of prayer under the direction of Rich Wallen. Eagle Creek Community Church Pastor Ed Hasnerl will serve as the Master of Ceremonies. Congress passed a joint resolution in 1952 establishing the first Thursday in May as the National Day of Prayer. President Harry S. Truman signed it into law.
