Jesus demonstrated the greatest love by his death on the cross. “Greater love has no one than this, that one lay down his life for his friends” (John 15:13). He commanded all his disciples to demonstrate this same great love. “This is my commandment, that you love one another, just as I have loved you” (John 15:12). His disciples are predestined to be conformed to the family image of the greatest love. It is not the outward appearance but the inner man or spirit man which takes on this image of the greatest love. The spirit man conformed to the likeness of the greatest love is called the spirit of excellence. This study examines the spirit of excellence. It shows how a spirit of excellence is developed and how it operates.
