1 Peter 1:18-19 knowing that you were not redeemed with corruptible things, like silver or gold, from your aimless conduct received by tradition from your fathers, but with the precious blood of Christ, as of a lamb without blemish and without spot.

What is the meaning of redeem?
To buy back, to get or win back, to free from what distresses or harms: such as to free from captivity by payment of ransom, to extricate from or help to overcome something detrimental, to release from blame or debt, to free from the consequences of sin, or to change for the better.
Repair, restore, to free from a lien by payment of an amount secured thereby to remove the obligation of by payment.
You’ve heard stories of kidnappings where money is demanded for the safe return of the hostage.
If a kidnapping in the 1800s took place and was successful – today all the money from it is gone, the hostage is now dead, and the kidnappers are too.
You are in distress, a hostage of sin.
Sin demands payment and the ransom is death.
Jesus paid that ransom, not with silver, gold, or money, but with His own blood, that is, His death!
Not just anyone’s death would do.
My death will not redeem you.
Your parent’s death can not redeem you.
But the death of Jesus does redeem you because He is without blemish and without spot, that is, without sin.
Sin cannot pay for sin.
Only sinlessness can pay the ransom.
Jesus did!
