His measurements are based on quality namely the degree of faith, hope and love that is being reflected in your church. I feel that one of the greatest challenges to the church today is the changing value system in our culture. Some of the statistics that we see, demonstrate that in many values there is very little difference between the way people behave in the church and the way non-Christians behave in the world. This is the number one challenge, but it involves several areas. Marriages are breaking up.
Families are in tension.
Children are growing up in families that are compartmentalized. Parents are materialistic. Many don't model giving and stewardship and they don't model holiness and godliness. Somehow the church is expected to pick up the reins and do what parents don't do. I think a related challenge is that people don't understand commitment.
