Who are we? Our identity as Christians comes from the fact that God has created us in his own image and that through Christ he has redeemed us. Genesis 2:25 states that Adam and Eve "were both naked and they felt no shame". When they sinned (Genesis 3), they realized that they were naked, and sewed leaves together to cover themselves. They were ashamed of who they were. In our fallen world, people often seek their identity in another facet of creation - work, achievement or sports - because they are often ashamed of who they are.
If we take this knowledge of who we are into the world of sports, it will help us deal with the pressure of the performance based culture. Of course, we want to do well.We play to win. The amazing thing is that understanding who we are can help us enjoy winning all the more because we don't expect from victory more than it is able to give. If we seek in victory our significance as people, we will be disappointed - not to mention how crushing defeat becomes. If we know who we are, with Rudyard Kipling we can "meet with triumph and disaster and treat those two imposters just the same".
