1 John 5:19

5:19 We know that we are from God, ¹  and the whole world lies in the power of the evil one.

[5:19]  ¹ tn The preposition ἐκ (ek) here indicates both source and possession: Christians are “from” God in the sense that they are begotten by him, and they belong to him. For a similar use of the preposition compare the phrases ἐκ τοῦ πατρός (ek tou patro") and ἐκ τοῦ κόσμου (ek tou kosmou) in 1 John 2:16.
