As a former, total, unchurched rebel, much of the above is totally dead on target.
If I were to add one thing, it would be this: most of the unchurched do not understand 'trust'. That is because most of them are convinced only themselves are fully trustworthy. But, once a Churched, very Biblical man, pointed out to me much of the root of my issues were related to the fact I wasn't taught what 'real trust' was .... well, the rest is history.
Very insightful. You have given me something to think long and hard about. Thanks!
