Insight 327: FaithSoaring Churches Provide Remedial Education on the Bible
Congregations seeking to transform do not make the assumption that just because someone has attended church for most of their lives means they understand the Bible and how it applies to a Christ-like lifestyle. It may even be necessary to engage in remedial Bible study to help people relearn [hopefully not learn for the first time] the basic tenets of Christian faith.
Just listen to the conversation that can happen between a life-long church member and an unchurched person who is truly seeking a genuine faith experience. It could scare you how little the churched person knows about their own faith.
