One truth that is prominent in the law of the Goel is that the Goel must pay the debt owed and the debt must be so totally paid that there will never be a thought in the mind of the one redeemed that the redemption is not complete. Jesus paid our debt as our kinsman so totally that there is nothing left to be paid. 

There was an event that stands forever in the annals of history as the day God dealt with the Sin Debt – once and for all and that day was the day the Jesus was crucified as the ransom payment for our sin. 

John 19:30 AMP says: When Jesus had received the sour wine, He said, It is finished! And He bowed His head and gave up His spirit.
