رِسَالَةُ يُوحَنَّا ٱلرَّسُولِ ٱلْأُولَى 3:10

بِهَذَا أَوْلَادُ ٱللهِ ظَاهِرُونَ وَأَوْلَادُ إِبْلِيسَ: كُلُّ مَنْ لَا يَفْعَلُ ٱلْبِرَّ فَلَيْسَ مِنَ ٱللهِ، وَكَذَا مَنْ لَا يُحِبُّ أَخَاهُ.

In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.
