I have been reading a lot lately and have appreciated Ed Stetzer's analysis of the church. Here he makes a good critique. This is from a larger article you can read here.
Now, I am not willing to say that a lack of converts is a sign of unfaithfulness. But, I am willing to say that too many change movements are not seeing lost people's lives changed. And I think that is the wrong kind of change.
So, my Reformed friends, let's not only read 1st, 2nd, and 3rd John (that is, John Calvin, John MacArthur, and John Piper), let's go plant some more churches. My emerging church friends, let's take a pause from the theological rethink and head into the neighborhood and to tell someone about Jesus. My missional friends, let's speak of justice, but always tell others how God can be both "just and the justifier of the one who has faith in Jesus." My house church friends, let's have community, but let's be sure it is focused on redemption. My Baptist friends, let's focus more on convincing pagans than Presbyterians. And, my charismatic friends, let's focus less on getting existing believers to speak in tongues and more on using our tongue to tell others about Jesus.
