The gifts of the Holy Spirit are literally the Lord Jesus Christ living His resurrected life through us. When the Lord was here on earth He did everything Himself. He did all the preaching, teaching, exhorting, delivering, and healing. Now, however, He has divided His life up among many members, which make up the Body of the Lord Jesus Christ, the New Testament local Church.
Every Christian has at least one of these motivational gifts of the Holy Ghost found in Romans chapter twelve, and in order for the church to be impacting and effective we must learn from God's Word and God's men what our gift is and how to use it.
