Therefore if there is any consolation in Christ, if any comfort of love, if any fellowship of the Spirit, if any affection and mercy, fulfill my joy by being like-minded, having the same love, being of one accord, of one mind. Let nothing be done through selfish ambition or conceit, but in lowliness of mind let each esteem others better than himself. Let each of you look out not only for his own interests, but also for the interests of others. (Philippians 2: 1-4)
Many people - even Christians - live only to make a good impression on others or to please themselves. But "selfish ambition or vain conceit" brings discord. Paul therefore stressed spiritual unity, asking the Philippians to love one another and to be one in spirit and purpose. When we work together, caring for the problems of others as if they were our problems, we demonstrate Christ's example of putting others first, and we experience unity. Don't be so concerned about making a good impression or meeting your own needs that you strain relationships in God's family.
