Ephesians 1:7

In whom; in Christ, God-man, the immediate worker of this redemption; for though the Father and the Spirit concurred to it, yet the redeeming work was peculiarly terminated in the Second Person. The other two Persons have a right of propriety to redeem us; Christ only a right of propinquity, as assuming our nature, and being of kin to us. We; we elect, before mentioned. Have redemption; freedom from the wrath of God, and curse of the law, to which we are obnoxious, and consequently the power of sin and tyranny of Satan, as the effects of the former. Through his blood; i.e. by the sacrifice of his death upon the cross, where his blood was shed. This was the price of redemption paid to God for us, and wherewith his justice being satisfied, we could no longer be detained under the custody of the devil, or the dominion of sin. Even the forgiveness of sins; redemption is not formally forgiveness, but causally, forgiveness being the effect of it; and it is mentioned not as the only or adequate, but the prime and principal fruit of redemption, and upon which the other depend. According to the riches of his grace: what he called glorious grace, Ephesians 1:6, here he calls riches of grace, meaning plentiful and superabundant grace, by a phrase frequently used by him elsewhere in the same sense, Romans 9:23, Romans 2:4,7.
