But maybe society needs more of them these days. Too many people more aware of their rights than their responsibilities.
There is a deep wisdom in self-sacrifice. To the foolish, it appears as if a saint is just suffering out of blind obedience to God, which is his obligation as a Christian. In reality, self-sacrifice proves our faithfulness to God and paves the way for greater reward, honor and responsibility in eternity.
Only there is a difference between subservience to human beings and self-sacrifice in obedience to God. I am no man's (or woman's) slave. Should God be telling me to do one thing, they can go so far as to threaten my life and they still won't see me bowing down. That includes employers. God will provide for me, regardless of if I get fired or not. On the other hand, if I feel God is calling me to be self-sacrificing to someone for the sake of the gospel, I will be. Going the extra mile for a Roman soldier was a good example of this (Matthew 5:41).
There are times when God calls us to be self-sacrificing and other times when He will not. Take Paul for instance. There were numerous times when he was miraculously delivered from his persecutors in order to continue his ministry (Acts 16:23-30, 2 Corinthians 11:33). Yet he eventually allowed himself to be martyred as the ultimate sacrifice, but only
after he had finished his ministry.
In a similar way, He likewise taught slaves that they were to serve their masters faithfully as long as they were bound to them, yet if they were given the chance to have the freedom to do as they pleased, they were to by all means take it. (1 Corinthians 7:20-22).
In short, the teaching was that Christians are free from all men and slaves only to God, yet willingly become slaves to men when God calls them to it if doing so might help bring others to Christ (1 Corinthians 9:18-22).
