Having role models in the ministry and looking up to great men of God is wonderful, however, we should never make it our goal to imitate these men. God made each one of us unique. When he called you to preach he didn't call you to imitate other men, he called you to preach His Word.
I can't quote Scripture like James Langston or Boyd Bingham. I can't tell jokes like Tony Hutson. I can't write songs like Craig Edwards. I can't sing like Lester Rolloff. I don't have the wisdom of Clarence Sexton or John MacArthur. I can't tell stories like Phil Kidd. I don't have the recognizable voice of Stinnett Ballew. I can't ring the rafters like Charles Lawson. I can't write books like Oliver Greene. I can't fill a revival tent like Ralph Sexton Jr. While I admire and listen to each of these men, I can only be me. It took me a while before I realized that fact.
I notice a lot of young preachers today trying to imitate certain preachers, use their catch phrases, etc... Let me urge you to just be yourself the way God made you. There is probably something about you that no other preacher possesses. Just preach the Word and be the genuine article.
