To prize the righteousness of faith was an element in the true knowledge of Christ; but it was so far from exhausting that knowledge, that it only opened a door of progress, and brought near the most stirring possibilities. For, indeed, to be found in Christ having that righteousness meant that God in Christ was his, and had begun to communicate Himself in eternal life. Now this must still reveal itself in further and fuller knowledge of Christ. According to the Apostle's conception, that which Christ means to be to us, that which we may attain to be by Christ, opens progressively to the soul that has been won to this pursuit; it comes into view and into experience in a certain growing knowledge. It is a practical historical career; and the Apostle was set on achieving it, not by strength or wisdom of his own, but by the continual communication of grace, responding to desire and prayer and endeavour. We must not forget, what has more than once been said, that this earthly life of ours is the scene in which the discipline goes on, in which the career is achieved. It is the calling here and now, not at some other stage of being, that the Apostle is thinking of for himself and for his disciples. And as earthly life is the scene, so earthly life also furnishes the occasions and opportunities by which the knowledge of Christ is to advance. Any other way of it is for us inconceivable. This life in all the various forms which it assumes for different men, in all the changing experiences which it brings to each of us--life on the earth we know so well--with its joy and sorrow, its labour and rest, its gifts and its bereavements, its friends and foes, its times and places, its exercise and interest for body and mind, for intellect and heart and conscience, with its temptations and its better influences,--life must furnish the opportunities for acquiring this practical knowledge of Christ. For that which falls to us, if we are in Christ, is a certain blessed well-being (itself an unfolding of Christ's wisdom and grace). And this must impart itself, and reveal itself, in our actual experience, but in an experience which we pass through under the guidance of Christ.
