The old notion is that a person must work to live. The more successful one is in their work, than the more comfortable they will live. Many people work for this greater life of wealth and comfort.
In contrast Jesus died so that all may live. Jesus never seemed to put to much stock in gaining material advantages, being wholly comfortable, or interpreting the importance of life by counting the number of possession one owns. Instead of being self serving he concerned himself with the lives of others.
Paul argues that all should live for him who died, and that this is true life -everlasting. The pattern we need follow in this life is to live more like Jesus. It is then that we find a life given and not earned. We are met by grace.
What life are you living for? How do these two notions meet and greet one another, or are they in conflict?
