Μὴ ἀγαπᾶτε τὸν κόσμον μηδὲ τὰ ἐν τῷ κόσμῳ. ἐάν τις ἀγαπᾷ τὸν κόσμον, οὐκ ἔστιν ἡ ἀγάπη τοῦ πατρὸς ἐν αὐτῷ· 1 John 2:15, NA28
Do not love the world nor the things in the world. If anyone loves the world, the love of the Father is not in him. 1 John 2:15, NASB
There is a certain type of love that God hates. We find that in John 15:18–20:
Εἰ ὁ κόσμος ὑμᾶς μισεῖ, γινώσκετε ὅτι ἐμὲ πρῶτον ὑμῶν μεμίσηκεν. εἰ ἐκ τοῦ κόσμου ἦτε, ὁ κόσμος ἂν τὸ ἴδιον ἐφίλει· ὅτι δὲ ἐκ τοῦ κόσμου οὐκ ἐστέ, ἀλλʼ ἐγὼ ἐξελεξάμην ὑμᾶς ἐκ τοῦ κόσμου, διὰ τοῦτο μισεῖ ὑμᾶς ὁ κόσμος. μνημονεύετε τοῦ λόγου οὗ ἐγὼ εἶπον ὑμῖν· οὐκ ἔστιν δοῦλος μείζων τοῦ κυρίου αὐτοῦ. *εἰ ἐμὲ ἐδίωξαν, καὶ ὑμᾶς διώξουσιν· εἰ τὸν λόγον μου ἐτήρησαν, καὶ τὸν ὑμέτερον τηρήσουσιν. John 15:18–20, NA28
“If the world hates you, you know that it has hated Me before it hated you. If you were of the world, the world would love its own; but because you are not of the world, but I chose you out of the world, because of this the world hates you. Remember the word that I said to you, ‘A slave is not greater than his master.’ If they persecuted Me, they will also persecute you; if they kept My word, they will keep yours also. John 15:18–20, NASB
God has no love for “love of the world system that is opposed to God.” Jesus made it clear in the passage from John 15:18-20 that those who are “of the world” are not of God nor are those whom He has selected from out of the world part of the world. This is why those who are still “of the world” hates them. I want to reinitiate here that there are plenty of apostate, “so-called Christians” in our time who exhibit that very same hatred toward those of us who refuse to back away from Orthodox Christianity and God’s Word and being infallible and complete. In any case, John is telling us in 1 John 2:15–17 two important truths about genuine Christianity. First, the Christian loves God and fellow Christians and an absence of love of the world must habitually characterize the love life of those to be considered genuinely born again.
