Matthew 8:11 I say to you that many will come from the east and the west, and will take their places at the feast with Abraham, Isaac and Jacob in the kingdom of heaven.
-I find this promising, and vaguely related to the illegal immigrants. My interpretation (which Is derived from the basic meaning of this) is Many will come to Christ, from across the world, to worship and follow him.
Luke 13:29 People will come from east and west and north and south, and will take their places at the feast in the kingdom of God.
-Pretty much the same meaning.
2 Peter 1:11 and you will receive a rich welcome into the eternal kingdom of our Lord and Savior Jesus Christ.
Full paragraph (as this that was cut off from this whole thing)
2 Peter 1:10-11 Therefore, my brothers and sisters, make every effort to confirm your calling and election. For if you do these things, you will never stumble, and you will receive a rich welcome into the eternal kingdom of our Lord and Savior Jesus Christ.
-This talks about how we must use our effort to follow Christ, our calling, and we will not stumble (not saying we will not struggle), and we will be welcomed into heaven (though I would consult a church father on the full meaning of this, as I admit I have my doubts of my interpretation),
Romans 14: This one talks about the concept of personal sins (again ask a church father, not me), and not judging a brother/sister in christ because of their actions (concerning personal sin). And a few other things such as being weary not to cause others to feel in despair as if you are sinning, and if they might do so because of your actions (not sinful, and not your own personal sin, but to them it is one),then you should change your actions out of love for them.
Again, don’t trust me for interpretation of this. TALK TO A CHURCH FATHER/PRIEST.
I don’t see how it really relates to illegal immigrants.
