What does Ephesians 2:6 mean?

In addition to being made alive in Christ (Ephesians 2:5), God has "raised us up with him." We are now alive through the same power that brought Jesus back from the dead. In the future we will be seated alongside Christ in "the heavenly places." Interestingly, Paul speaks of this action as if it has already taken place. He assumes it is only a matter of time before it takes place. He held great confidence that those who have truly come to faith in Christ can anticipate future eternity with the Lord. Paul teaches elsewhere that nothing can separate us from the love of God in Christ Jesus (Romans 8:37–39). First John 5:13 adds that God wants believers to know—to be confident—that we have eternal life.

The idea of "heavenly places" is mentioned only in Ephesians. Paul has already noted "heavenly places" in Ephesians 1:3 and 1:20. In Ephesians 3:10, he will speak of the wisdom of God now made known to those in the heavenly places. In Ephesians 6:12, Paul speaks of our battle being against spiritual forces of evil in the heavenly places. The phrase speaks of more than just heaven, but rather the entire spiritual world beyond the known physical realm.
