“Although he was sent to the Gentiles, Paul always had a deep love for his own people Israel (e.g., Rom. 3:1; 9:1–3). Paul’s early training in the law and his learning of a trade (tent-making) reveal that he came from a family who lived by true Israelite ideology.”
The above quote is From: Survey of the New Testament, by Paul N. Benware
Patriotism is the feeling of love, devotion, and a sense of attachment to one’s country. Patriotism is good within the confines of that definition. Without getting too political, I believe it’s fine to love your country as long as you don’t make an idol of it. Many have made patriotism an idol, but that’s a story for another time.
