Despite his reputation as a fiery preacher, Jonathan Edwards actually spoke in a quiet and dignified voice. Rather than shouting and gesturing wildly, he relied on striking imagery and the logic of his arguments to make his points. “My conversation and my preaching were not with persuasive words of wisdom, but with a demonstration of the Spirit and of power, so that your faith would not be based on human wisdom but on the power of God.” (1Cor. 2:4, 5) Shouting never proved a point. A quiet witness in the power of God’s Spirit is the only amplifier He needs.
