Philippians 2:3-6

Let nothing be done through strife or vainglory; but in lowliness of mind let each esteem other better than themselves. Look not every man on his own things, but every man also on the things of others. Let this mind be in you, which was also in Christ Jesus: who, being in the form of God, thought it not robbery to be equal with God
