Philippians 2

Because the followers of Jesus were to be assisting one another in their lives and character development, they needed to imitate the mindset of Jesus. This is the mindset that puts others' needs and well-being ahead of one's own - even when that results in pain, suffering and even death. This is the example Jesus left for His followers. Now His followers are to live lives that mirror that self-sacrificing, others-serving pattern without a grudging attitude or complaint. It is a joy to be used in the development and betterment of others. This is the pattern Paul himself followed, traveling from place to place encouraging others. When he was unable to personally travel, others were sent with messages from him. The goal for each one (Paul, Timothy, Epaphroditus) was to assist others in the growth into Christ-likeness.
