I Thessalonians 3:12
12 And may the Lord make your love for one another and for all people grow and overflow, just as our love for you overflows
Why didn't Apostle Paul just say, may the Lord make your love for one another grow and overflow ......
Why did he add, "and for all people?"
Could it be that he was pointing us to unconditional love. We tend to shun away from others if they do not align with our beliefs, convictions, etc.
We often tend to view "one another" as "one of us."
