Alright, so in 2 John 1, we've got the author, who is a beloved pastor, addressing a church. He tells them to love one another, to walk in truth, and to abide in the doctrine of Christ. He warns them not to be deceived by false teachers, and to look out for those who don't believe in Christ. He also tells them to be generous and welcoming to strangers, and to show hospitality to those who are in need. And that's all folks!
