Note 13 at Eph. 1:7: The Greek word used here for "redemption" is APOLUTROSIS and is used 10 times in the New Testament (Lk. 21:28; Rom. 3:24; 8:23; 1 Cor. 1:30; Eph. 1:7, 14; 4:30; Col. 1:14; Heb. 9:15; 11:35). This word literally means "the releasing effect or liberation procured by the payment of a ransom" (Thayer).

Matthew 20:28 and Mark 10:45 make it clear that the price paid for our redemption was the life of Jesus, that is, Jesus' blood (Col. 1:14). This redemption, according to Hebrews 9:12, was eternal and was intended to purify us from all iniquity (Ti. 2:14), and bring us to serve the living God (Heb. 9:14). See ref. s at this verse for more footnotes on redemption.

Note 14 at Eph. 1:7: Paul is saying that it is through the riches of God's grace that we received forgiveness for our sins. There is nothing we can do to obtain forgiveness except humble ourselves and receive forgiveness as a gift through faith in Christ (see note at Eph. 2:8).
