We learn in this passage that the unity of the church can be disrupted by people teaching contrary doctrines. Have you ever experienced this? Talk about this experience. How were these people able to fool some people and not others? If this was in a church, what was the response from church leadership? Use your discretion in using actual names - this doesn't need to become a time of slander or gossip. How do we avoid this as a church?
We have an enormous amount to be thankful for, but we take so much for granted. Take time as a group to talk about all of the ways God has blessed you throughout this year.
