For gold to become useful, it has to go through the fire. The same is true for Christians. For the servant of God to be used for his kingdom in service, one must first travel through the refining furnace and become a broken vessel before one can be a shining light. In Integrity in His Service, writer Ralph E. Champagne shows the importance of integrity in our service to God. Without integrity, one can't fully offer their life up to God. We can't go on living with the darkness in our lives. We must test ourselves and rid our whole being of any inequity so that the light we have can shine all the brighter.
