“ The Word that will change a man must first show the man who he really is. ”
The (bible) teacher predicts and defines the route and pace of the spiritual growth of his students. This is because it is to the degree of the knowledge of CHRIST in a disciple that we can measure his spiritual growth.
~ Christian Michael
The end product of the successful preacher's input is transformation.
As food is to the body, so is The Word to the Spirit of a disciple
Unless you understand the difference between insight and revelation, you will be far from transformation.
