Every animal on earth has a set of correspondences with the environment around it, and some of these correspondences far exceed ours. Humans can perceive only 30 percent of the range of the sun’s light and 1/70th of the spectrum of electromagnetic energy. Many animals far exceed our abilities. Bats detect insects by sonar; pigeons navigate by magnetic fields; bloodhounds perceive a world of smell unavailable to us.
Perhaps the spiritual or “unseen” world requires an inbuilt set of correspondences activated only through some sort of spiritual [awakening]. “No one can see the kingdom of God without being born from above,” said Jesus (John 3:3 NRSV). “The person without the Spirit does not accept the things that come from the Spirit of God but considers them foolishness, and cannot understand them because they are discerned only through the Spirit,” said Paul (1 Corinthians 2:14 NIV). Both expressions point to a different level of correspondences available only to a person spiritually alive.
