God gave Reverend Grace a vision to establish a place of worship which he proceeded to do not knowing how, with what, when or where, but with his faith he worked to make his vision a reality.
He found an unoccupied building on Norfolk Street in Dorchester, Reverend D. L. Grace and his family began to spend long hours converting this building to Timothy Baptist Church, a place where people could come to worship. It was his faith and determination that gave him the inspiration to continue even though it meant using household moneys, going without some necessities and many sleepless nights.
