A.W. Tozer:

Much of church activity and fellowship also falls back upon the practice of psychology. Many church leaders are masterful psychologists. They know how to handle people and get the crowds to come. Their operation qualifies as an amazingly “successful” church. Part of the success of that church depends on people with business talents and part of it depends on people with natural gifts as salespersons and politicians.

A Christian congregation can survive and often appear to prosper in the community by the exercise of human talent and without any touch from the Holy Spirit. But it is simply religious activity, and the dear people will not know anything better until the great and terrible day when our self-employed talents are burned with fire and only what was wrought by the Holy Spirit will stand.

 – Tozer, Tragedy in the Church: The Missing Gifts, 22-23

When we assess spiritual leadership, let us not be guilty of evaluating psychologists, salespersons, politicians, and talented businessmen rather than shepherds of the flock, servants of Christ, and stewards of the gospel.
