Arthur Stace, or Mr Eternity as he became known, left his mark all over Sydney in the mid 1900s. He wrote only one word— ‘eternity’—in beautiful copperplate script with chalk on pavements from Martin Place to Parramatta. Why did he do this thousands upon thousands of times over more than 30 years? On the night of 6 August 1930 Stace walked into St Barnabas Church on Broadway and heard the preaching of RBS Hammond. Something impacted Stace that changed his life for… eternity.
