Unlike a thermometer, which could only measure the temperature, the thermostat could change the environment by raising or lowering the temperature. With a thermidistat, however, we can now control the humidity levels in the house, as well as the temperature.

Temperature and humidity levels is what spells comfort in a home. In a church, as well, the temperature can make the difference between a church that attracts people and one that distracts people.

By temperature, of course, I am speaking of something more profound than the number indicated on the thermometer. Congregational climate is set, not by an air conditioner or furnace, but by a variety of factors—confidence in the power of the gospel to change lives and in the congregation to be an agent of that gospel, the love and care members have for each other and for strangers, a contagious sense of expectancy rooted in a strong faith in God, trust between the pastor and the laity, a commitment to excellence and quality, and, always, a deep trust and reliance on God.
