I get the frustration with inefficiency in churches (skimmers: the article points out that senior leaders don't attend their local churches because they get frustrated with how they're run). But I have to laugh at myself because God uses what appears to me to be some of the most inefficient methods known to man to get stuff done. Parking Moses in the desert for 40 years, allowing faithful leaders like Daniel to spend their entire lives in captivity, letting David get hunted by his own king, etc. And good ole apostle Paul would sympathize, too, but for different reasons. Look at the moral atrocities found in the early church--sex, lawsuits, divisions, etc.
No, sir, not efficient at all.
