In Philippians 3, Paul is reflecting on his past and contemplating his future.  In looking back, he says that all he had gained in the past he considers to be loss.  He calls is garbage or rubbish.  Now, that he knows Christ, his values have changed, his priorities have changed, and he is focused on different and better things.  As he looks to the future, he describes it as a track race.  He says he has not crossed the finish line yet, he hasn't attained the prize or the medal yet.  But, he is pressing on and straining for what is ahead.  God has something really good waiting for you in your future.
