And if you call on the Father, who without partiality judges according to each one’s work, conduct yourselves throughout the time of your stay here in fear; 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. He indeed was foreordained before the foundation of the world, but was manifest in these last times for you who through Him believe in God, who raised Him from the dead and gave Him glory, so that your faith and hope are in God.
Listen to the "Verse by Verse" episode covering this scripture.
No amount of money could pay the penalty of our sins, but Jesus Christ gave His priceless blood for us. Peter reminds us how awesome this sacrifice is and how that should make us repentant and fearful of continuing in sin.
God did not leave Jesus in the grave, but resurrected Him and gave Him the glory He had before coming as a human being. Jesus Christ’s sacrifice and resurrection confirm our faith and hope in God, who promises to forgive and resurrect those who repent, believe and obey Him.
