Brothers and sisters while I find this discourse intriguing, I would caution against calling ourselves "slaves." The word slave defined means: 1)a person held in servitude as the chattel of another 2)one that is completely subservient to a dominating influence 3)a device, as the printer of a computer that is directly responsive to another. God hasn't called us to be slaves, not to him and certainly not to any other person or pursuit. He has called us to be servants. The difference being that servants can choose who or what they will serve, slaves cannot. Our mission is always first to serve Him. We thank the Lord for the opportunity, the desire and the gift to do what we do, but we can never be "slaves" to it because that is not what he has ordained for us. So to make the most of what He has given us we study and practice, and work to perfect our craft becacuse ultimately what we seek is for our playing to be a reflection of Him in us. Our goal is to take what He has given to us and give it back to Him. That's ministry. And through our ministry, we have the capability of touching others through music and song which I would consider a by-product, if you will, of our true purpose. As we endeavor to perfect our craft through long hours of practice and study and maybe putting aside some things that aren't really so important in the grand scheme of things, we get to the point where we are honestly and truly serving the Master, and serving the music, and serving his people.
