Summary: 1) The Redeemer (Ephesians 1:6b), 2) The Redeemed (Ephesians 1:7a) , 3) The Redemption Price (Ephesians 1:7b), 4) The Results (Ephesians 1:7c-9a), and 5) The Reason (Ephesians 1:9b-10).
A common tactic among ISIS insurgents is the practice of taking hostages for ransom. They seize journalist, soldiers or people that identify with their enemy, like Christians, for the purpose of receiving a ransom from their host nation. If the host countries cannot extract their citizens by force, they tend to redeem their citizens from this captivity by payment.
During New Testament times the Roman Empire had as many as six million slaves, and the buying and selling of them was a major business. If a person wanted to free a loved one or friend who was a slave, he would buy that slave for himself and then grant him freedom, testifying to the deliverance by a written certificate. Lutroō was used to designate the freeing of a slave in that way.
That is precisely the idea carried in the New Testament use of the term to represent Christ’s atoning sacrifice on the cross. He paid the redemption price to buy for Himself fallen mankind and to set them free from their sin.
Every human being born since the Fall has come into the world enslaved to sin, under total bondage to a nature that is corrupt, evil, and separated from its Creator. No person is spiritually free. No human being is free of sin or free of its consequences, the ultimate consequence, or penalty, for which is death (Rom. 6:23). “The soul who sins will die” (Ezek. 18:4).
Redemption is one of the central themes of Scripture and of the book of Ephesians, but it carries much more than the idea simply of exchanging one thing for another of equal value. In Ephesians 1:6b-10, the Apostle Paul shows the Road to Redemption by showing five elements of the redemption God offers fallen humanity through His Son, Jesus Christ: 1) The Redeemer (Ephesians 1:6b), 2) The Redeemed (Ephesians 1:7a) , 3) The Redemption Price (Ephesians 1:7b), 4) The Results (Ephesians 1:7c-9a), and 5) The Reason (Ephesians 1:9b-10).
1) The Redeemer (Ephesians 1:6b)
Ephesians 1:6b (to the praise of his glorious grace, with which) he has blessed us in the Beloved. (ESV)
From the beginning of Jesus’ ministry the Father declared Him to be “My beloved Son” (Matt. 3:17). When we believe in Him, “He delivered us from the domain of darkness, and transferred us to the kingdom of His beloved Son” (Col. 1:13). Because we are now in the Beloved, we, too, are “beloved of God” (Rom. 1:7). To be Beloved represents one who is in the state of being loved by God. Jesus Christ is our Redeemer from sin, who Himself paid the price for our release from sin and death. Because we now belong to Christ, by faith made one with Him and placed in His Body, we are now acceptable to God. The perfect participle reaches into the past and extends into the present and the future. Christ is “the One Beloved” because of his mediatorial obedience to God (Lenski, R. C. H. (1937).
