Revealed by the Spirit

Paul revealed Christ by the simplicity of preaching to the Corinthians, it was the Spirit who brought the effectiveness. With the "mature" he spoke wisdom, but not his own--that which was revealed by the Spirit. That wisdom is noneless than the mystery of the gospel. With both believers and unbelievers, the responsibility of the preacher is to preach the mystery of the Gospel and the Holy Spirit enables people to "get" it.
