1 Corinthians 5:7-8
Get rid of the old yeast [i.e., of sin, and especially the unrepentant sinner], so that you can be a new batch of dough, without yeast in it [i.e., a godly church without unrepentant sinners in it] as [I know] you really are. For our Passover [Lamb], Christ, has already been sacrificed.
1 Corinthians 10:13
Every temptation that you have experienced is one that commonly happens to people. But God is dependable and will not allow you to be tempted beyond your ability [to cope with it]; [instead] He will provide, along with the temptation, also a way of escaping [it], so you people will be able to endure it.
2 Corinthians 1:9-10
Actually, we felt within us that we had [already] received a death sentence, so that we could [learn] not to trust in ourselves but in God, who raises the dead.
1 Peter 1:19-20
but with [the] precious blood of Christ, who represents an unblemished lamb, without defect.
