Paul’s letter to the Ephesians has been called “The Mount Everest of Paul’s theology”. He certainly takes us high-into the heavenlies – and he has developed earlier ideas, including speaking of “heavenly places” 5 times,starting in 1:3:
“Blessed be the God and Father of our Lord Jesus Christ,who has blessed us in Christ with every spiritual blessing in the heavenly places…..”
If we are “in Christ” we live then, in a different sphere…. the heavenlies. Jesus came to where we were (Hebrews 2:14-18) in order to take us where He is (John 14:3)…… and Paul amplifies that that is now, not just when we die. Good News!
