This quote by George Whitefield recommends that our time in the world is restricted and that we are just mortal till we have finished our purpose or objective. It suggests that each individual has a particular function or task to meet during their time in the world, and once that is achieved, they become never-ceasing in a sense. This could be translated as a belief in an afterlife or a tradition that lives on after we die. It also stresses the significance of satisfying our purpose and making the most of our time in the world. In general, this quote encourages us to review our purpose and make every effort to meet it before our time in the world is over.
"I was married to Margaret Joan Howe in 1940. Although not a scientist herself she has contributed more to my work than anyone else by providing a peaceful and happy home"
