The Two Become One

“[God] raised us up together, and made us sit together in the heavenly places in Christ Jesus.”
EPHESIANS 2:6

Just as certainly as the Vine was crucified, dead, buried, resurrected, ascended and seated, so the Branches were crucified, dead, buried, resurrected, ascended and seated. The whole issue is: will we abide in the Vine and share in the overcoming, or not? Overcoming is bound up with abiding. The Lord says, “Live in Me, and I will live in you.”
Now the Lord says that overcomers will sit with Him in His throne. How is that possible? Because we are in Him, and He is in us: “He who is joined to the Lord is one spirit with Him” (1 Corinthians 6:17), and “The two shall become one” (1 Corinthians 6:16).
