What Should Christians Be Doing?

To answer the question about what can or should we do about what is going on in our country. The answer depends on why God blesses you. Does he bless you so you can go on vacations and have expensive cars, large houses etc or so you can give more, so you can help others more.
 
Our culture, the culture of capitalism, more for me, less for you, has diverted Christians from working on their purpose. We shrug off the question what would Jesus do saying he does not want us to be poor etc. If we were to identify a place in the world that would be difficult for us to survive we most probably would avoid it. Considering Jesus said, "Truly, I say to you, only with difficulty will a rich person enter the kingdom of heaven" why would any Christian want to be rich?
 
Paul told Timothy: "I urge that supplications, prayers, intercessions, and thanksgivings be made for all people,  for kings and all who are in high positions, that we may lead a peaceful and quiet life, godly and dignified in every way.  This is good, and it is pleasing in the sight of God our Savior,  who desires all people to be saved and to come to the knowledge of the truth. For there is one God, and there is one mediator between God and men, the man Christ Jesus, who gave himself as a ransom for all, which is the testimony given at the proper time." 
 
To me that says it is good and pleasing in the sight of God that we lead peaceful, quiet lives because he desires all people to be saved, not so we can have comfortable lives and go on great vacations, live in large homes, buy nice cars etc. Our culture tells us differently and in that way our culture has diverted us from our purpose.
 
What should we do? What should Christians do?  Help the people to come to the knowledge of the truth would be a good start and stop looking to our own pleasures, security, comforts. Paul told Timothy "whoever knows the right thing to do and fails to do it, for him it is sin" what part don't Christians undrstand?
