Philippians 2:4

“not looking each of you to his own things, but each of you also to the things of others”

“Not”: This verse tells us how we are to consider one another above our own selves. “Looking”: “Present active. Not keeping an eye on the main chance for number one” (Robertson p. 444). “Attentively: fixing the attention upon, with desire for or interest in. Hence often to aim at” (Vincent p. 430). Each of you to his own things”: Self-interest is simply being primarily interested in yourself. "Self" being the main focus of your mental thoughts. “Seek not your private ends alone” (Con). “Stop looking after your own interests only” (Wms). Obviously, this never meant that one can never take care of thier own needs or interests (Ephesians 5:28). Hence, the NASV translators added the word "merely".

“But each of you also to the things of others”: Be impressed with the phrase, "each of you". This level of maturity is not merely required of elders, deacons and preachers, is it required of all members. Looking to the true and best spiritual interests of others, is the foundation of Christian ethics (Galatians 6:2; Romans 15:1). “The more one realizes how fervently Christ loved the brother, and went all out to save him, the more he will wish to advance that brother's interests” (Hendriksen p. 101). “For the Christian there is no road that by-passes his fellowman” (Muller p. 76).

The one mind: The mind of Christ

“Verses 6-11 presents Jesus as the supreme example of the humble, self-sacrificing, self-denying, self-giving service that Paul has just been urging the Philippians to practice in their relations one toward another” (Hawthorne p. 79). Claiming to follow Christ imposes certain obligations upon us. It is fruitless to call oneself. Christian, if one is unwilling to admire and put into practice the example and mind-set of the Jesus that one claims to love (1 John 2:6 “the one who says he abides in Him ought himself to walk in the same manner as He walked”.)
