John 15:19

τὸ ἴδιον. Its own. In John 7:7 He told His brethren, who did not believe on Him, that the world could not hate them. This shews why. In their unbelief it still found something of its own (1 John 4:5). The selfishness of the world’s love is thus indicated. It loves not so much them, as that in them which is to its own advantage: hence the lower word φιλεῖν rather than ἀγαπᾷν (contrast John 15:17); it is mere natural liking. With the solemn repetition of κόσμος comp. John 3:17; John 3:31; John 12:36; John 17:14. For the construction comp. John 5:46; John 8:19; John 8:42; John 9:41; John 18:36 and contrast John 4:10; John 11:21; John 14:28. For διὰ τοῦτο see on John 7:21-22.
