Eph 1:11 NLT
Furthermore, because we are united with Christ, we have received an inheritance from God, for he chose us in advance, and he makes everything work out according to his plan.
The Inheritance
This inheritance we have already received. Paul will go deeper into what this inheritance is in the coming chapters and verses. But the point here is that, we have received, past tense, this inheritance.
We have received this inheritance because we are united in Christ. We are in other words, one with Him (Christ).
Who
Again we go back to verse 1, those who are faithful believers in Christ. He didn’t say that He chose those who believe, but those who believe He has chosen.
What
His plan for His people, and all created things will be completed.
