What does Philippians 3:13 mean?
Paul's goal is perfection, but he has not reached it yet. He is not faultless, nor does he expect to achieve perfection before his death. Instead, he uses the analogy of a runner in a race to depict the motivation of his spiritual life. Like a dedicated runner, he has a single goal. Just as a runner cannot be successful unless they concentrate on the race, neither can Paul be successful growing in Christ if he allows other goals to interfere.Continuing the running analogy, Paul also chooses to live by an important principle: keeping his attention on the road in front of him. A runner cannot look back and still focus on the goal ahead. The two ideas are mutually exclusive. A runner's goal is to focus on the next step toward his or her goal. Paul's spiritual life is the same. He will not look back to past steps, but focus on improving each step in his race until reaching the goal of being with Christ.
Christians can learn from the past, but we are not bound to the things we have done. Instead of being chained by our past mistakes, we can move forward, knowing that we carry Christ's forgiveness.
