Why Is This Section Called Redeemed?

What does Redeemed mean? Here's how Noah Webster defined it in 1828:

Redeem v.t.
1. To purchase back; to ransom; to liberate or rescue from captivity or bondage, or from any obligation or liability to suffer or to be forfeited, by paying an equivalent; as, to redeem prisoners or captured goods; to redeem a pledge.

Redemption is a transaction, whether a trade or a purchase, where something is traded for another thing of equal value. But it's a purchase through which the thing bought is returned to its rightful state.

We who have believed that Jesus' death on the cross paid the penalty for our sins have been redeemed. Before we believed, we were worthy of damnation because we could not live according to God's perfect Law.

Here's how the apostle Paul explains it in the book of Galatians: "Cursed is everyone who does not abide by all things written in the book of the Law, to perform them. [That's us] …Christ redeemed us from the curse of the Law, having become a curse for us, for it is written, 'Cursed is everyone who hangs on a tree….' God sent forth His Son, born of a woman, born under the Law, so that He might redeem those who were under the Law, that we might receive the adoption as sons." (Galatians 3:10, 13; 4:4-5)

There we see from what we have been redeemed, and to what we have been redeemed. We were sinful and worthless to God (Romans 3:10-12)As it is written, "There is none righteous, not even one; There is none who understands, There is none who seeks for God; All have turned aside, together they have become useless; There is none who does good, There is not even one." incurring a debt, which was a punishment of death. That debt had to be paid if we were to go free. Then God in His great compassion and lovingkindness sent His Son to earth. Jesus Christ took that punishment in His death on the cross, and our debt was paid. Thus we were redeemed from condemnation, and now have been made children of God! (Galatians 4:5...so that He might redeem those who were under the Law, that we might receive the adoption as sons.; John 1:12But as many as received Him, to them He gave the right to become children of God, even to those who believe in His name)

Christ Jesus—who gave Himself for us to redeem us from every lawless deed, and to purify for Himself a people for His own possession, zealous for good deeds. Titus 2:14

We are now the redeemed people of God, zealous for good deeds, eager to spread the good news of redemption to all people.
