“knowing that you were not redeemed with corruptible things, like silver or gold, from your aimless conduct received by tradition from your fathers.”
that you were not redeemed
In the first century, “redeemed” conveyed the idea to purchase from the marketplace of sin. God sets Christians free as captives enslaved to captors.
In the Roman Empire, “redemption” was used primarily with the slave market. When Rome conquered nations, they sold their citizens into slavery. The only possible way to gain freedom was that someone should buy them out of the slave market. Manumission of a slave necessitated the price of a ransom posited at the shrine of a god.
How did we become slaves to sin? How did we end up in the slave market of sin? Jesus said that if we commit one sin, we become the slaves to sin (John 8:32-36). All members of the human race are, therefore, in the slave market of sin (Rom. 3:10,23).
Jesus personally paid for our salvation. He came with the right purchasing power. He bought us out of the slave market of sin.
Jesus personally paid the price for our redemption.
Redemption gives an individual the right to be forgiven because Jesus paid the price for forgiveness. This frees the forgiven person to live for God without strings attached. We love God freely because Jesus paid the price for our sins.
