As Christians, we are called to live a life that is different, so that we cause the world to become different. Christ's instructions for his disciples and the people he interacted with were in contrast to the ways of the world. One way that we can be successful in this call to a different life is by being intentional about serving others. The American dream seems to be all about making life better for "me" and "my own". But we are called to something better, something different- maybe if more people stopped looking out for #1, we would end up with more people looking out for us than just ourselves.
So this week, look after the needs of someone other than you. Go "do something good every day" because Christ did something incredible for them.
"Each of you should look not only to your own interests, but also to the interests of others." Philippians 2: 3 (NIV) (bold added)
