But here’s a danger: it’s so easy for Theology Network groups to become cosy clubs for Christians, where we feel comfortable because nobody challenges us in our beliefs and everyone agrees with us.  There’s nothing wrong with enjoying spending time with other Christians (in fact, there’s a real problem if we don’t! cf. John 13:35), but we have to be careful that the teaching in the group doesn’t become a matter of training to win arguments, and that the evangelism we do doesn’t become something like throwing gospel bombs over battlements.  Instead, the focus has to remain on Christ and his great good news.  We come together to encourage each other in the gospel, and equip ourselves for persuasive and winsome witness to our friends – and then we go and hang out with them!
