Purge out therefore the old leaven, that ye may be a new lump, as ye are unleavened. For even Christ our passover is sacrificed for us:
Paul is writing to the early church in Corinth, a city in ancient Greece, and he is troubled by serious sin the community has been quietly tolerating. He reaches for a powerful image from Jewish tradition: before Passover — the annual feast celebrating God's rescue of Israel from slavery in Egypt — Jewish families would search their entire homes and remove every trace of yeast, also called leaven. Yeast symbolized corruption because a tiny amount spreads invisibly through an entire batch of dough. Paul tells the church to clean out sin the same way. Then he makes a stunning theological move: Christ is the Passover lamb. In the original Passover story, a lamb was sacrificed so that death would pass over the homes of God's people. Paul declares that sacrifice has already happened in Jesus — and the implications are enormous.
Lord, thank you that the Lamb has already been sacrificed and that my cleanness isn't something I have to earn. Show me the old yeast I've made peace with, and give me the courage to remove it. I want to live as what I actually am: new. Amen.
There's something almost violent about a proper Passover house-cleaning. You pull out the furniture, check behind the refrigerator, go through old coat pockets — every crumb has to go. Paul borrows this image not to shame the Corinthians but to remind them of something they seem to have forgotten: they're already clean. 'As you really are,' he says. Not 'as you're trying to become.' The sacrifice has been made. The Passover Lamb has already bled. Living in old patterns isn't just spiritually dangerous — it's a lie about who you've become. That's the harder read of this verse. It isn't 'clean yourself up so God can accept you.' It's 'you ARE a new batch — so stop living like you're still the old one.' What old yeast have you kept around, maybe because it's familiar, maybe because letting go feels like losing something you've built a life around? A bitterness quietly nursed, a habit you've quietly made peace with, a version of yourself you haven't quite let die. The Lamb has been sacrificed. You're already free to be new.
Paul says 'as you really are' — as if being a new batch without yeast is already the Corinthians' true identity, not a goal to achieve. What does that tell you about how Paul views believers even when they're failing?
What 'old yeast' — a habit, attitude, pattern, or mindset — have you kept holding onto even after coming to faith? What has made it difficult to remove?
Paul wrote this in response to a church tolerating serious sin in its community. How does a community 'remove old yeast' without becoming harsh or self-righteous? Where is that line, and who gets to draw it?
If your identity as 'new' is already true — not earned, not pending — how should that change the way you treat other believers who are still struggling with old patterns?
Is there one specific 'old yeast' you're ready to name this week? What would it look like — practically, not just spiritually — to begin removing it from your life?
But with the precious blood of Christ, as of a lamb without blemish and without spot:
1 Peter 1:19
Who verily was foreordained before the foundation of the world, but was manifest in these last times for you,

So get rid of this "yeast." Our true identity is flat and plain, not puffed up with the wrong kind of ingredient. The Messiah, our Passover Lamb, has already been sacrificed for the Passover meal, and we are the Unraised Bread part of the Feast.
