They are of the world] Wicked and unregenerate men, John 15:19. and John 17:9. therefore speak they of the world, &c.] Because they are of the world, they speak sutably, and are heard readily: for, being sensuall themselves, 1 Corinthians 2:14. and speaking to such as themselves, of things pleasing to them, as they have learned by their senses; here men readily hearken to them. John 3:31.
