I'm a Bible believer, but we have a Constitution, not a Biblical monarchy.
That said, even with strict border control and expulsion of every illegal, the U.S. takes in far, far more than its share of legal immigrants, from any perspective.
One of the things that Constitution guarantees is the right for believers to push for government policies that agree with their beliefs. There is no endorsement in this article of unconstitutional or extra-constitutional policies.
I'm with you, Larry. The author expressed very well something I've long thought but didn't put into writing:
Failure to enforce the law has created this problem, and the ironic aspect is that the very blessing illegal aliens come here to secure for themselves is precisely a result of an economy and society made strong by the rule of law.
