In answer to why it’s important to count people in the Church.

My answer:

Whilst it’s not all about the numbers, numbers are important to know how many people we’re reaching and so that we can measure the effectiveness of what we do.

Someone cared enough to count in the gospels: 5,000, 12, 72, 40, 3000 - the numbers of those present, disciples, those sent out, days, number of people saved at Pentecost.  

Numbers help us to work better, cater better, welcome better, have enough house groups, have enough leaders, have enough chairs, have enough baptismal pools, the list goes on.
