2 Peter 2 is about false teachers.  This chapter is a wake-up call that there are some really, really bad people in the world.  Peter gives us a long description about all of the evil things these people do.  He tells us about God's appropriate judgment on them.  But, he also tells us that God knows how to rescue godly people from their trials.  Are you going through some trials right now?  If so, and if you put your trust in Jesus, God can rescue you from them and lead you back to a better place.
