The first consideration is what is the law of the land. Those who illegally enter any country have violated that nation’s law. The Bible makes it clear that those who violate laws are sinning as are those who support or assist them in breaking the laws. 1 Peter 2:13-17 is very clear that we are to obey the law and that the government is to punish those who break the law. We are not to hate or do violence toward them but we are to support the enforcement of the law.
