Philippians 2:3 is an interesting verse, but the last part of it is difficult (for me) to understand, and, at least as it is often translated, could easily be interpreted as paradoxical.
NIV: Do nothing out of selfish ambition or vain conceit, rather in humility value others above yourselves
ESV: ... count others more significant than yourselves
NASB: ...regard one another as more important than yourselves
KJB: ...let each esteem other better than themselves
Do not imagine that if you meet a really humble man he will be what most people call “humble” nowadays: he will not be a sort of greasy, swarmy person, who is always telling you that, of course, he is nobody. Probably all you will think about him is that he seems a cheerful, intelligent chap who took a real interest in what you said to him. If you do dislike him it will be because you feel a little envious of anyone who seems to enjoy life so easily. He will not be thinking about humility: he will not be thinking about himself at all.
