Paul, an apostle of Christ Jesus by the will of God, To the saints in Ephesus, the faithful in Christ Jesus:
Grace and peace to you from God our Father and the Lord Jesus Christ.
Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ.
For he chose us in him before the creation of the world to be holy and blameless in his sight. In love, He predestined us to be adopted as his sons through Jesus Christ, in accordance with his pleasure and will—to the praise of his glorious grace, which he has freely given us in the One he loves.
In him we have redemption through his blood, the forgiveness of sins, in accordance with the riches of God’s grace that he lavished on us with all wisdom and understanding.
And he made known to us the mystery of his will according to his good pleasure, which he purposed in Christ, to be put into effect when the times will have reached their fulfillment—to bring all things in heaven and on earth together under one head, even Christ.
In him we were also chosen, having been predestined according to the plan of him who works out everything in conformity with the purpose of his will, in order that we, who were the first to hope in Christ, might be for the praise of his glory.
And you also were included in Christ when you heard the word of truth, the gospel of your salvation. Having believed, you were marked in him with a seal, the promised Holy Spirit, who is a deposit guaranteeing our inheritance until the redemption of those who are God’s possession—to the praise of his glory.
GNT … The power that energizes our salvation is the same power God used to raise Jesus from the dead and establish Him as the supreme authority in the Universe, Paul said. And now he makes the unbelievable claim that by this same power we too are raised up and have been seated there with Him. Not will be, but have been. Jesus is King of Kings and Lord of Lords, with authority over any power you can name, and we’re right there beside Him!
With that Paul has informed us that both The Father and the Holy Spirit dwell within us. Jesus had already indicated that He dwells there too. With this distinguished trio going everywhere we go doing everything we do, it’s no wonder Paul felt compelled to provide a 3 chapter directive on how we should behave.
