Christians must identify the issues these new neighbors present. Most important is the awareness that these people are dying and going to hell. Another way to make an impact is simply to be a friend and to help them make the necessary adjustments. A trip to the grocery store or other shopping places is difficult when you do not speak the language. Be patient and willing to understand them, instead of demanding they understand you.
People respond to friendship and love.
Love them as Jesus does. Many Christians are unsettled by the demographic changes taking place in America. We need to see people as those for whom He paid a great price.
