A unique feature of Christianity is the seemingly backwards social hierarchy. With unbelievers, there are great divisions between "greater" and "lesser" people. The "lesser" serve the "greater", and the "greater" accept, and even demand, that it stays that way. However, in Christianity, first of all there is true equality between men. We all have different roles, but no one is truly greater than another.
But it gets better than that, for there is actually a way to be considered greater. How? By acting like you are the lesser. Jesus exemplified this, because He, being God, is of course far greater than any man, yet He came in the form of a servant. He didn't choose to be born as the heir to a throne. He chose a humble maidservant, engaged to a carpenter. He didn't hang out with the religious elite, He went around eating with penitent sinners. He had no servants, but He worked Himself to the point of exhaustion making sure everyone else's needs were met. Jesus washed feet.
This is how Christians should be. Regardless of who we are, or what role we play, we should always act as if we were the servants of others. No one should try to lord it over his fellow man. We shouldn't be trying to dominate or abuse each other. What right have we to boast? If we happen to have some kind of "great" attribute, it is a gift from God, and do we imagine He will be pleased if we misuse that? The husband is the head of the wife, but Christ is the head of the Church. Christ served the Church, a husband should serve his wife. An employer has authority over his employee, but God has greater authority over His servants. If we are cruel masters, will our Master show us favour? Every parent has power over their children, but our God is our Heavenly Father. When we provoke our children, we provoke our Lord.
With all this in mind, let us keep the Philippians 2:3 mindset: Let nothing be done through selfish ambition or conceit, but in lowliness of mind, let each esteem others better than himself. As far as you are concerned, your needs are irrelevant compared to your brother's. As Christ humbled Himself, setting aside even His Heavenly glory to become obedient even to death, so also should we set our needs and desires aside to serve one another. That is the true nature of Christianity.
