A friend in need.

Romans gives us a pretty clear picture in terms of what we're supposed to do for other people.

Everything.

We give it our all.  If it is physically possible it says in Romans 12:18, live at peace with everyone.  You should take notice that in that verse it does not say, "If you get a chance to, live at peace with those who are peaceable." Instead, it says "If possible, as far as it depends on you", which for those who don't speak old archaic languages means "If it is in your power to obtain, or in the realm of physically capabilities or possibilities".

Then it continues to humble us further saying "live at peace with everyone".

It's hard for some people to live at peace with others.  It's especially hard when you have the commandments of God telling you not only love them, but that you owe it to them.  In Romans 13:8 Paul says "Owe nothing to anyone-except for your obligation to love one another.  If you love your neighbor, you will fulfill the requirements of God's law."  We take a sharper turn down spiritual alley and we say something even more alien to our society: Not only should we take all efforts possible to love one another, but we owe it to them.  Forget the money we owe, the economy we're in and our mortgages.  Love one another.  Love is your debt.  May we always try to pay it with abundant interest.
