To be filled with the Spirit is to be controlled by the Spirit. The Christian leader’s mind, emotions, will, and physical strength all become available for the Spirit to guide and use. Under the Spirit’s control, natural gifts of leadership are lifted to their highest power, Through the work of the now ungrieved and unhindered Spirit, all the fruits of the Spirit start to grow in the leader’s life. His witness is more winsome, service more steady, and testimony more powerful. All real Christian service is but the expression of Spirit power through believers yielded to Him (John 7:37–39).
