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.
Berean Study Bible (BSB) - 1 John 3:10 >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.
Textus Receptus (TR) - 1 John 3:10 >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 ἀδελφὸν αὐτοῦ.
