Paul has just been laying down a great principle--viz. that if the main direction of a life be right, God will reveal to a man the points in which he is wrong. But that principle is untrue and dangerous, unless carefully guarded. It may lead to a lazy tolerance of evil, and to drawing such inferences as, 'Well! it does not much matter about strenuous effort, if we are right at bottom it will all come right by-and-by,' and so it may become a pillow for indolence and a clog on effort. This possible abuse of a great truth seems to strike the Apostle, and so he enters here, with this 'Nevertheless,' a _caveat_ against that twist of his meaning. It is as if he said, 'Now mind! while all that is perfectly true, it is true on conditions; and if they be not attended to, it is not true.' God will reveal to a man the things in which he is wrong if, and only if, he steadfastly continues in the course which he knows and sees to be right. Present attainments, then, are in some sense a standard of duty, and if we honestly and conscientiously observe that standard we shall get light as we journey. In this exhortation of the Apostle's there are many exhortations wrapped up; and in trying to draw them out I venture to adhere to the form of exhortation for the sake of impressiveness and point. I. First, then, I would say the Apostle means, 'Live up to your faith and your convictions.' It may be a question whether 'that to which we have already attained' means the amount of knowledge which we have won or the amount of practical righteousness which we have made our own. But I think that, instead of sharply dividing between these two, we shall follow more in the course of the Apostle's thought if we unite them together, and remember that the Bible does not make the distinct separation which we sometimes incline to make between knowledge on the one side and practice on the other, but regards the man as a living unity. And thus, both aspects of our attainments come into consideration here. So, then, there are two main thoughts--first, live out your creed, and second, live up to your convictions.
