1 Peter 1:18-19

18 knowing that you were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers, 19 but with precious blood, as of a lamb unblemished and spotless, the blood of Christ.

In our evaluation of things, seeing what value Christ put on us, that He gave His very life-blood for us (His precious blood; unblemished), this may influence your conduct.
