People tend to wrongly attach a moral value to church size. This explains why big churches are accused of being uncaring and small churches are accused of not reaching people or being well-led or organized…. [Some] will accuse those who care about numbers to be simply pragmatic, as if wanting more people to meet Jesus and grow in grace was a bad thing. After all, the fourth book of the Bible is called Numbers, and Acts likes to often tell us how many people were in the early church, such as 120 in the beginning and then the exact thousands that were added at various points…. If a church is unwilling to change their methodology to reach and care for more people, then it is guilty of methodolatry, which is where we confuse unchanging biblical principles with what are supposed to be changing cultural methods.
