Fullness of Time
The reference to the fullness of time in Ephesians is more difficult. Some translations understand the time when all things are gathered together in Christ to lie in the future (NIV, TEV); others, in the past (REB). A major theme of Ephesians is that Christ has already broken down the dividing wall of hostility between Jew and Gentile (1 John 2:11-22 , especially 1John 2:14,1 John 2:21 ). Therefore, it seems likely that the crucial shift in time between the past with its hopelessness and hostility and the present age of reconciliation has already occurred.
