If that is "seeker sensitivity" then I am against it. Any Church which tells sinners that they ought to feel good about themselves is doing those sinners no good.
On the other hand, if by "seeker sensitivity" you mean that a Church goes out of its way to bring people to a place where they can be confronted by their sin, where they can be presented with a well preached gospel message and where they can be given the opportunity to respond to the gospel and exercise saving faith in Christ and where they can grow spiritually through the teaching of the whole counsel of God, then I'm all for it.
I think that one of the problems in the critique of "seeker sensitive" churches is that authors such as the one above do not clarify what the term means. They just lump all churches that might be viewed as having an open door to those who are not yet saved as being "seeker sensitive" and then slander those churches by claiming that they do not preach the gospel.
Well I dare say that if a lot of those who are critical of "seeker sensitive" churches were to think back, they'd realize that they came to Christ when they did because someone had been sensitive to their condition and went out of their way to be sensitive to their spiritual quest and to point them in the right direction and to bring them to the place where they had to confront the risen Lord.
I don't think that is the way tht seeker sensitive is being used in this context.
