Jesus also said we should to render unto Caesar the things that are Caesar's.
In this case Caesar, our government, has laws that regulate immigration.
In other words Jesus is telling me to be kind to the stranger and alien, but he also saying the law must be obeyed. And if the law is to be obeyed, then illegals should not be here in this country.
Do you disagree with this interpretation? And if so, how?
You have this issue correct.
It has to do with the kingdom of the Right and the Left.
The Right being the Kingdom of God, the believers who practice forgiveness and Grace.
The Kingdom of the Left is the government we have set in place. We have chosen those who implement our laws. It is the government that regulates the laws that we live under. It is they who are to implement the laws. They are NOT doing their job. They even take an oath to do that and they are ignoring their duty.
It is wrong to confuse the two parts. People often do. Tolerating illegal activity (law breaking) is wrong.
Forgiving those who sin is compassionate and God-like.
