And if that be so, then the nature of the thing to be laid hold of determines what we are to do to lay hold of it. And since to know Christ, and the power of His Resurrection, and the fellowship of His sufferings, is the aim and end of our conversion, the way to secure it must be keeping in continual touch with Jesus by meditating upon Him, by holding many a moment of still, sacred, sweet communion with Him, by carefully avoiding whatever might come between us and our knowledge of Him, and the influx of His life into us, and by yielding ourselves, day by day, to the continual influence of His divine grace upon us and by the discipline which shall make our inward natures more and more capable of receiving more and more of that dear Lord. These being the things to do, in regard to the inward life, there must be effort too, in regard to the outward; for we must, if we are to lay hold of that for which we are laid hold of by Jesus Christ, bring all the outward life under the dominion of this inward impulse, and when the flood pours into our hearts we must, by many a sluice and trench, guide it into every corner of the field, that all may be irrigated. The first thing they do when they are going to sow rice in an Eastern field is to flood it, and then they cast in the seed, and it germinates. Flood your lives with Christ, and then sow the seed and you will get a crop. III. Lastly, the text suggests the incompleteness of our grasp. 'I follow that,' says Paul, 'if that I may apprehend.' This letter was written far on in his career, in the time of his imprisonment in Rome, which all but ended his ministerial activity; and was many years after that day on the road to Damascus. And yet, matured Christian and exercised Apostle as he was, with all that past behind him, he says, 'I follow after, that I may apprehend.' Ah, brother, our experience must be incomplete, for we have an infinite aim set before us, and there is no end to the possibilities of plunging deeper and deeper and deeper into the knowledge of Christ, and having larger and larger and larger draughts of the fulness of His life. We have only been like goldseekers, who have contented themselves as yet with washing the precious grains out of the gravel of the river. There are great reefs filled with the ore that we have not touched. Thank God for the necessary incompleteness of our 'apprehending.' It is the very salt of life. To have realised our aims, to have fulfilled our ideals, to have sucked dry the cluster of the grapes is the death of aspiration, of hope, of blessedness; and to have the distance beckoning, and all experience 'an arch, wherethro' gleams the untravelled world to which we move,' is the secret of perpetual youth and energy.
