Jesus knows that his departure is close at hand. In light of this, he prays to the Father, acknowledging that his disciples are not of the "kosmos" or system of the world, though they will be witnesses to the world. Other sections of scripture, 1 John 2:15 and 1 Corinthians 9:19 provide practical content on areas in which Christians should adopt the practices of the world/culture, and areas in which Christians should be different from the world and culture.
