We refrain from returning evil for evil not only because it is the right course but also because it is the loving course. Note how the apostle Paul next considers the motive of love.
(‏ روما ١٢ :‏ ​ ١٤ ،‏ ١٧ -‏ ١٩ ،‏ ٢١‏ )‏ إِنَّ كَلِمَاتِ بُولُسَ هذِهِ لَا تَدَعُنَا فِي حَيْرَةٍ بِحَيْثُ لَا نَعْرِفُ كَيْفَ يَلْزَمُ أَنْ نُعَامِلَ غَيْرَ ٱلْمُؤْمِنِينَ ،‏ حَتَّى ٱلْمُقَاوِمِينَ بَيْنَهُمْ .‏
