Jesus declared that he is not of this world, while his opponents are of this world. (John 8:23). This contrast of an upper and a lower world is more related with Jewish contrast between the present world and the world to come. [C. K. Barrett, The Gospel According to St. John: An Introduction with Commentary and Notes on the Greek Text, 2nd ed. (London: SPCK, 1993), 35.] I am trying to find other relation to this concept in Logos. How can I do this?
