Redeem: exagoridzo = permanent removal from captivity

Because this word is used in connection with Jesus redeeming us from the curse of the law, Paul is telling us plainly that Jesus’ sacrificial death didn’t only pay the penalty for our sin; His death removed us from living under the curse henceforth!  His ultimate plan was to buy you out of [your] miserable condition and then to place you in His family as His own child.  You are forever removed from the curse of sin and the law.  

Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, “Cursed is everyone that hangeth on a tree.”
Galatians 3:13
