The whole modern culture is revolved around making themselves big - wanting all the power and interest for themselves. Rather Paul says something different which replicates Christ, "do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others" (Philippians 2:1-11). We are to give up everything for Christ since he has given up everything for us, walking in humility and not self gain.
