In 1996, Brother Witness Lee began to minister concerning the full ministry of Christ in three stages. Most of his speaking has been published in the books Incarnation, Inclusion, and Intensification and How to Be a Co-worker and an Elder and How to Fulfill Their Obligations. While speaking to an international gathering of co-workers and elders, Brother Lee said, "To be able to speak these things thoroughly and clearly, you need to learn. If you want to know how to be elders and co-workers, you need to know Christ and to experience, enjoy, and gain Him according to all that He has accomplished and is accomplishing in the three stages of His full ministry." In order to help all the brothers and sisters learn the truths concerning the full ministry of Christ in three stages, the corresponding message outlines have been set to music. May these spiritual songs help us to learn these truths that we may be "perfected unto the work of the ministry unto the building up of the Body of Christ."
