Parallel
1 John 3:10
Nestle 1904 Greek New Testament · Berean Standard Bible
ἐν τούτῳ φανερά ἐστιν τὰ τέκνα τοῦ Θεοῦ καὶ τὰ τέκνα τοῦ διαβόλου πᾶς ὁ μὴ ποιῶν δικαιοσύνην οὐκ ἔστιν ἐκ τοῦ Θεοῦ καὶ ὁ μὴ ἀγαπῶν τὸν ἀδελφὸν αὐτοῦ
By this the children of God are distinguished from the children of the devil: Anyone who does not practice righteousness is not of God, nor is anyone who does not love his brother.
