The Measure of Church Growth

How can we measure church growth?

Many things are contingent on being able to measure church and mission growth.
I know they are Jesus's churches, but men are overseers of those churches. Jesus runs His churches perfectly. Yet the men placed in leadership positions are flawed, they are sinners, they make mistakes, and some have evil motives.

Spiritual growth is more important than numerical growth, I agree, but you show me how to measure that and I'll run with it.
I do believe spiritual growth will lead to numerical growth.

So, what numbers do we go by?
Professions of faith. Read mission reports the number of Professions look good, but look next to that number and see how many are following in obedience with baptism. That number is 75-95% lower than the number of professions.
Should we lessen the significance of a profession and place more significance on the number baptized?
I think there is a hunt for Numbers. Those seeking support are out to count anything that looks like a profession. You can see this clearly in the SBC, but you can see it in the ABA as well.

My question is how do we measure?
