Let’s understand exactly what this verse means.
Ephesians 2:6 in the Authorized Version of the Bible says God “hath raised us up together, and made us sit together in heavenly places in Christ Jesus.”
This verse is speaking of Christians now. Certainly we are not in heaven right now. Yet the verse says we are now sitting together in “heavenly places,” whatever those are.
The word heavenly in this verse is translated from the Greek word epouranios, which refers to something high or lofty. It does not have to refer specifically to heaven.
Notice also that the word places is in italics. That means the word was not in the original Greek text, but was later added by translators. The verse literally says that we have been made, now, to “sit together in heavenly [or heavenlies] in Christ Jesus.”
Ephesians 2:6 is saying that with God’s Spirit leading us, we look at things from God’s point of view, setting our minds “on things above, not on things on the earth” (Colossians 3:2). We become “ambassadors for Christ” (II Corinthians 5:20), called out of this world as “a royal priesthood… His own special people” (I Peter 2:9), to teach and set the example of God’s perfect way of life, which is so different from the way this world lives.
We are, even now, in a relationship of high and lofty terms and conditions — we have indeed had the “heavenlies” opened to us!
Ephesians 2:7 refers to what will happen in the future — “in the ages to come.” When God’s Kingdom is set up, we shall reign as kings and priests with Christ on earth (Revelation 5:10). Christ promises that we shall actually sit with Him on His throne on earth at that time (Revelation 3:21).
Ephesians 2:6 in no way contradicts John 3:13 and dozens of other scriptures that prove conclusively that Christians do not go to heaven.
