I like this quote by Calvin Miller:
"Style--the inimitable trait is composed of chromosomes, DNA, and the ricochet of an honest soul off the environment around it. It all adds up to the most admirable of all preaching traits. Envy Swindoll, Spurgeon, and Peter Marshall if you will, but even they cannot exposit the Word as only you can. Do not envy them for their style. Their popularity is but a little edge that declares their style but does nothing to detract from your own. Being who you are is much easier than trying to be who they are, and it is so much more authentic and useful to your listeners. But more than authentic, it is properly persuasive. We never have more power to influence an audience than when we are busy about being ourselves and telling the world how we feel about God and his expectations for the church and the human race."
I think that these comments on style go beyond the act of preaching. I think that they apply to living. God became flesh for a reason. Christ dwells within believers for a reason. I think it is because there is nothing more powerful than "the ricochet of an honest soul off the environment around it."
