We are redeemed by the precious blood of Christ

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.—1 PETER 1:18,19

Being redeemed is a tremendous concept. Redemption was a technical term for money paid to buy back a prisoner of war. It has the idea of paying a ransom to set someone free. We needed to be redeemed from the useless, aimless life passed down by tradition from our fathers. We needed to be rescued from that because the way of the world is the way of death and judgment. We are redeemed by the precious blood of Christ. He alone was the acceptable sacrifice to God who paid the price for our sins. And He is pictured as a Lamb without blemish and without spot because throughout the Old Testament the whole sacrificial system of animals being offered as sin offerings to God all looked forward to the coming of the Lord Jesus Christ, who would be the final lamb. Which is why very soon after His death the city of Jerusalem was destroyed by the Romans in 70 A.D., and with that destruction, the entire sacrificial system came to an end. To this day there has never been a temple or a place for sacrifice, and none is needed because Jesus was the final sacrifice.
