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 patros) and ἐκ τοῦ κόσμου (ek tou kosmou) in 1 John 2:16.
