1 Corinthians 5

1 Corinthians 5:6
Do you not know that a little leaven leavens the whole lump?
 
A little mold. A little bacterium. A little cancer. A little sin. You don’t need to worry about something so small. A little is not going to hurt anything.  
 
We all know that’s not the attitude to take. When it comes to these things, a little will eventually turn into a lot. So, excise it before it gets out of hand. This chapter encourages us to take a hard stance against sin. We can’t get soft or complacent, thinking that a little won’t hurt anything. No, it needs to be cut out. It may not be fun, and it might not be pleasant, but the results of ignoring sin, will always be much, much worse. A little leaven leavens the whole lump.
