Parallel
1 John 3:10
Robinson-Pierpont Byzantine Textform · 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.
