This seems like such a simple quote. I was going to let it stand without commentary, but I realized that this is really the essence of the convictions of all Christians who are passionate about social justice. To be a Christian is to care, in a self-emptying, physical, sacrificial way, for others. And to recognize that the things we do now have ripples down through history, on generations not yet born.
This quote expresses why we have a responsibility to act on environmental issues, on racial issues, on issues of poverty and inequality–the whole range of questions that are the most uncomfortable to address, because they challenge cherished ideals of self-reliance and rugged individualism.
