1 Corinthians 5:7
Get rid of the old leaven, that you may be a new unleavened batch, as you really are. For Christ, our Passover lamb, has been sacrificed.
Ephesians 5:2
and walk in love, just as Christ loved us and gave Himself up for us as a fragrant sacrificial offering to God.
Hebrews 10:1, 11, 12
For the law is only a shadow of the good things to come, not the realities themselves. It can never, by the same sacrifices offered year after year, make perfect those who draw near to worship. / Day after day every priest stands to minister and to offer again and again the same sacrifices, which can never take away sins. / But when this Priest had offered for all time one sacrifice for sins, He sat down at the right hand of God.
