There will always be Christians who will rightly and necessarily point out that we must present Christ and not ourselves. They will say that we are in danger of entwining law and gospel. I concur completely with the danger these watchmen see and find of great concern, but I would counter with a similar set of warnings against equally dangerous overreactions.
Discipleship is a constant concern among Christians; perhaps one of the largest concerns among Christian leaders. But ask typical church leaders how many intentional discipleship ministries they have that are not strictly classroom shaped. The answer likely will be awkward, with the standard confession that this is an area where "we need improvement."
