Matthew Poole and continuators on Ephesians 1:14

14 Which is the earnest of our inheritance until the redemption of the purchased possession , unto the praise of his glory .

The Spirit given to, and dwelling in Believers by his Gifts and Graces is the earnest or pledge whereby their Inheritance is secured to them, as Men are secured the payment of a promised Sum, by a part given beforehand in earnest for the rest.

Either 1. the Redemption of the Possession is put for the Possessing of the Redemption (by an Hypallage) viz. full and final Redemption from Sin, and Death, and Hell, and Satan; which Redemption though perfectly wrought by Christ, is but in part applied in this Life, and is to be fully enjoyed in the other; or 2. rather (though to the same sense) to the full and final Redemption in the end of the World, of all God's people who are here called his Purchased Possession: see the same word so taken, Act 20.28. and 1 Pet. 2.9.

The final Salvation, and complete Redemption of God's people, will be especially for the Glory of God, 2 Thess. 1.10.
