What is the Christian Response to Illegal Immigration

Some feel that as Christians we should have open borders and allow those less fortunate to come into the U.S. and find the American dream.
Others see that allowing millions of immigrants to continue coming to the U.S. will eventually destroy our economy and place our security in grave danger, especially since many terrorists will also come.

Should we feel guilty or selfish if we want to keep out immigrants?
If a person thinks it all the way through, to permit illigal immigrantion means providing them a home and finding them a job. Compassion means we want to love others and treat them as we would want to be treated.
But is this logical?

God placed civil government in its role of authority to prevent chaos and injustice.
The job of federal government is to protect the survival of the country and its citizens.
If there is no country then there is nothing to govern or protect.
Two of the ten commandments are do not steal and do not lie.
Crossing into America illegally breaks both of these comandments. That's why it's called illegal.
Just as it is wrong to break into someone's home it is also sinful to break into another country unlawfully.

Illegal immigrants are here under false pretenses.
Unless this country is granting them political asylum because their life is being threatened ,they should return to their own country or be deported.
The U.S. government has set up measures for foreign citizens to legally become U.S. citizens.
If the government chooses to pardon those already living in the U.S. that is the governments perogative.

The civil government has a Biblical mandate to maintain law and order for the good of siciety.
