"Now I myself am confident concerning you, my brethren, that you also are full of goodness, filled with all knowledge, able also to admonish one another" (Romans 15:14).
Paul gave thanks for the faith of the Roman Christians: "First, I thank my God through Jesus Christ for you all, that your faith is spoken of throughout the whole world" (Rom. 1:8). Now, he briefly outlines why he was confident they would follow the instructions he gave them. Each of his reasons are expressions of their faith, and by them we are exhorted to follow their good examples. First, Paul had confidence in them because they were "full of goodness." Their virtue was genuine, not pretended. Nor was their goodness partial. Their lives were filled up with goodness. Next, Paul had confidence in them because they were "filled with all knowledge" (Eph. 5:17-18). Their knowledge of God's word filled every part of their being. It informed their faith, their hope, their motives, and their conduct (John 8:31-32). Thirdly, Paul had confidence in them because they were "able also to admonish one another." They were situated to effectively caution and reprove each other because of their goodness and knowledge of God's word. Knowledge standing alone puffs up (1 Cor. 8:1). But, when coupled with goodness one is equipped to admonish and to be listened when that warning is needed. We enhance our ability and opportunity to help one another be faithful by maturing our faith in goodness, in knowledge, and in the ability to admonish others from God's word.
