BONUS - Those Who Say “This World Is Not Our Home” To Justify Avoiding Cultural/Political Issues

How should we respond to those who say “this world is not our home” in order to justify not getting involved in the culture war and politics? Many Christians point to Bible verses that describe us as “sojourners” and “strangers” in order to support their avoidance of the tangible issues of our day. Are these Christians right? Are we merely sojourners in this world? Or does the Bible have a different message for New Testament Christians?
