There can be no be no better instruction... than that every man who is to deal with his neighbor to follow these commandments. 'Whatsoever ye would that others should do unto you, do ye also unto them,' and 'Love thy neighbor as thyself.' If these were always followed, then everything would instruct and arrange itself; then no law books nor courts nor judicial actions would be required. All things would quietly and simply be set to rights, for everyone's heart and conscience would guide them.
Martin LutherIt is with all these qualities that we must stand before God and intervene on behalf of those who do not have them, as though clothed with someone else's garmentBut even before men we must, with the same love, render them service against their detractors and those who are violent toward them; for this is what Christ did for us.
Martin LutherWhat is it to serve God and to do His will? Nothing else than to show mercy to our neighbor. For it is our own neighbor who needs our service; God in heaven needs it not.
Martin Luther
