So, dear brethren, seeing that by our own faults the possession is incomplete, and seeing that in the incompleteness there is given to each of us, if we rightly use it, a mighty power which is working ever towards the completion, it becomes us day by day to draw into our spirits more and more of that divine influence, and to let it work more fully upon the sins and faults which, far more than the body of flesh, or the connection with the world which it brings about, are the reasons for the incompleteness of the possession. We have, if we are wise, the task to discharge of daily enclosing, so to speak, more and more of the broad land which is all given over to us for our inheritance, but of which only so much as we fence in and cultivate, and make our own, is our own.
The incompleteness is progressively completed, and it is our work as much as God's work to complete it. For though in our text that redemption is conceived of as a divine act, it is not an act in which we are but passive. The air goes into the lungs, and that oxygenates the blood, but the lung has to inflate if the air is to penetrate all its vesicles. And so the Spirit which seals us unto the redemption of the possession has to be received, held, diffused throughout, and utilised by our own effort.
II. Now, secondly, notice the certainty of the completion of the incompleteness.
As I have already said, the clod of earth and the handful of grass, the servant's wages, the soldier's shilling, are all guarantees that the whole of the inheritance or of the pay will be forthcoming in due time. And so there emerges from this consideration of the Divine Spirit as the 'earnest,' the thought that the present experiences of a Christian soul are the surest proofs, and the irrefragable guarantees, of that perfect future. We ask for proofs of a future life. They may be very useful in certain states of mind, and to certain phases of opinion, but as it seems to me, far deeper than the region of logical understanding, and far more conclusive than anything that can be cast into the form of a syllogism, is the experience of a soul which knows that God is its, and that it is God's. 'I think, therefore, I am,' said the philosopher. 'I have God; therefore I shall always be,' says the Christian. Whilst that evidence is available only for himself, it is absolutely conclusive for himself. And the fact that it does spring in the hearts which are purest, because nearest God, is no small matter to be considered by men who may be groping for proofs of a life to come. If the selected moments of the purest devotion here on earth bring with them inevitably the confidence of the unending continuance of that communion, then those who do not believe in that future have to account for the fact as best they may. As for us who do know, though brokenly, and by reason of our own faults very imperfectly, what it is to have God, and be had by Him, we do not need to travel out to dim and doubtful analogies, nor do we even depend entirely upon the fact of a risen Christ ascended to the heavens, and living evermore, but we can say, 'I am God's; God is mine, and death has no power over such a mutual possession.'
The very incompleteness adds strength to the assurance, for the facts of the Christian life are such as to demand, both by its greatness and by its littleness, by its loftiness and by its lapses into lowliness, by the floodtide of devotion that sometimes sweeps rejoicingly over the mud-shoals and by the ebb that sometimes leaves them all black and festering, a future life wherein what was manifestly meant to be, and capable of being, dominant, supreme, but was hampered and hindered here, shall reach its full development, and where the plant that was dwarfed in this alien soil, transplanted into that higher house, shall blossom and bear immortal fruits. The new moon has a ragged edge, and each of the protrusions and concavities are the prophecy of the perfect orb which shall ere long fill the night with calm light from its silvery shield. The incompleteness prophesies completion.
