But Peter used the word “alien” to describe you and me. Of course he meant those who are foreigners in this world, who do not belong here,in other words, extraterrestrials. He also used the word “pilgrims” or “sojourners,” meaning those who avoid attachments that would impede the journey to their final destination (1 Peter 2:11).
Paul, too, saw himself as an alien from outside of space and time—a foreign ‘life form’ transported through time in a body (1 Cor. 15). But unless you know the reality of your co-death and co-resurrection with Jesus (Romans 6; Galatians 6), I am afraid this idea may be alien to you. Do you think Paul had this in mind when he scolded the Corinthians for acting like “mere men” (1 Cor. 3)?
