"Abundant life" is a term used to refer to Christian teachings on fullness of life. It is not an organized movement or a unique doctrine, but a name applied to the teachings and expectations of the groups and people who follow the teachings. Abundant life teachings may include expectations of prosperity and health, but may also include other forms of fullness of life when faced with adverse circumstances.
It’s quite clear that success has nothing to do with our initial set of circumstances. Some of the most poor and disadvantaged people in the world have achieved the greatest successes of all time. Oprah Winfrey was born to a single mother on welfare and was physically and sexually abused as a child. J.K. Rowling was divorced, had a daughter, and was living on government assistance before publishing the first book in the Harry Potter series.
