In addition to keeping a good conscience, serving ones must also learn to exercise their mingled spirit. There is a problem among the full-timers today that we do not exercise our spirit enough in our service. The first point of contact in our coming and going should be our spirit, but unfortunately it is often our soul. This is because our spirit is too weak. We need to exercise our spirit so that it becomes the prominent part of our being, dominating our soul and directing us in how to shepherd others. Paul speaks of the importance of serving in spirit in Romans 1:9, 7:6, and 12:11. God is constantly working and active, however, He must first stir us up in our spirit, where He is living, to cause us to work with Him. If our spirit is weak and puny we will not be able to move in tandem with the Spirit.
