I hope you will take the time to write a short list of things you’ve learnt, or been reminded of, from reading How to Lead Group Bible Study so that People Meet God.
Otherwise the danger is that a week later we’ve forgotten everything we thought we’d learnt.
And, whether or not you have worked through the book with a friend, it absolutely makes sense to meet up with someone for a coffee and tell them the things that have struck us most and which we want to build into the way we prepare and lead group Bible study.
