And Jacob dreamed that there was a ladder set up on the earth, the top of it reaching to heaven; and the angels of God were ascending and descending on it. (Genesis 28:12)
“Be at peace with your own soul; then heaven and earth will be at peace with you. Enter eagerly into the treasure house that is within you, and so you will see the things that are in heaven; for there is but one single entry to them both. The Ladder that leads to the kingdom is hidden within your soul. Flee from sin, dive into yourself, and in your soul you will discover the stairs by which to ascend.” (St. Isaac the Syrian, from Kallistos Ware, The Orthodox Way, p. 71)
The counter intuitive insight of the Orthodox Christian spiritual tradition is that to find one’s way to God’s Kingdom, one does not look outside of one’s self – one doesn’t look to the heavens, but rather one has to learn how to go inward, into one’s heart and mind for there is where God has placed the way to Heaven. God is not out there somewhere – distant, remote, transcendent – God is found within us.
Being asked by the Pharisees when the kingdom of God was coming, Jesus answered them, “The kingdom of God is not coming with signs to be observed; nor will they say, ‘Lo, here it is!’ or ‘There!’ for behold, the kingdom of God is within you.” (Luke 17:20-21)
As the Prophet Isaiah testifies:
For thus says the high and lofty One who inhabits eternity, whose name is Holy: “I dwell in the high and holy place, and also with him who is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite. (Isaiah 57:15)
