Parallel
1 John 3:10
Patriarchal Greek New Testament (1904) · Berean Standard Bible
ἐν τούτῳ φανερά ἐστι τὰ τέκνα τοῦ Θεοῦ καὶ τὰ τέκνα τοῦ διαβόλου. πᾶς ὁ μὴ ποιῶν δικαιοσύνην οὐκ ἔστιν ἐκ τοῦ Θεοῦ, καὶ ὁ μὴ ἀγαπῶν τὸν ἀδελφόν 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.
