What does the Bible say about redemption by Christ?

In Galatians 4:3-7, the Apostle Paul explains the concept of redemption as a crucial aspect of God's plan for humanity. We are told that before the fullness of time, we were in bondage under the law. However, God intervened by sending His Son, Jesus Christ, made of a woman and made under the law, to redeem us. This act of redemption is not merely about being freed from sin; it also encompasses liberation from the law itself that once bound us. Thus, redemption is a comprehensive salvation that includes being adopted as sons and heirs of God through Christ.
