Ephesians 1:13-14

And because of him, when you who are not Jews heard the revelation of truth, you believed in the wonderful news of salvation. Now we have been stamped with the seal of the promised Holy Spirit. He is given to us like an engagement ring, as the first installment of what’s coming! He is our hope-promise of a future inheritance which seals us until we have all of redemption’s promises and experience complete freedom—all for the supreme glory and honor of God!
