The particle
εἰ
expresses here neither a doubt nor even merely possibility; for that the world hates the children of God is not merely possible, but in the nature of the case necessary; it is only the form of the sentence, and not the thought of it, that is hypothetical;[223] comp. Joh_15:18, also Mar_15:44.
[223] Ebrard explains
εἰ
incorrectly: “whenever the case occurs,” for the hatred which is here spoken of is not a frequently occurring case, but a necessary relationship. Braune unintelligibly says: “by
εἰ
John signifies that his readers as a whole or as individuals have after all at present no hatred to endure.”
