When the apostle Paul is writing to the church in Corinth (2 Cor 8:7), he is commending them: "You do well and excel in every respect." He is naming five areas in which they excel before he tells them to make suer that they excel in a sixth area. Even when he says that they excel in every respect, he is kind of saying that they can excel in more areas. There is always room for improvement. There is always the possibility of growing and maturing. If you excel, you have laid the foundation on which you may excel even more!
