We are expected to welcome people into our land and neighborhoods who are not necessarily our neighbors. According to Scripture, a neighbor is one who behaves as a Christian. Permanently immigrating non-neighbors into our land violates Yahweh God’s Law and plan for the holiness and separation of His people.
We have a false doctrine that we are to love everyone and forgive unrepentant sinners. This false teaching has “made us tolerant of all sorts of evil and of evil-doers” living in our communities.
Here is an article (PDF) on the subject. It is dated as the author passed away in 1985, but you will only have to read a couple pages to see what scripture really teaches about loving everyone including the wicked. Feel free to skim.
