What does Ephesians 1-6 constantly drive home about believers?
Ephesians 1–6 constantly drives home that believers are now positioned in Christ, in His body, and in the heavenlies. The 90-some prepositional phrases such as 'in Him' and 'in whom' define this peculiar position: believers are not an earthly people but a heavenly people, though still on earth.
Les explains that Ephesians has 90-some prepositional phrases in its 6 chapters, and they always denote our position in Christ—'in whom,' 'in Him,' 'in this,' or 'in that.' The whole 6 chapters are constantly driving home that believers are now in a peculiar position. Unlike Romans, which shows that we were hell-bound, filthy, wicked sinners and then gives the Gospel remedy—Christ has already forgiven us, died for us, paid the payment, and we appropriate it by believing—Ephesians does not deal with those problems. Instead, it hammers home the fact that you are now positioned in Christ, in the body, with the roots of that position seen in verse 3. Les says we are positioned in the heavenlies; we are not an earthly people but a heavenly people, though we are still on the earth.
