We have no difficulty in solving the riddle of the prophecy by the light of history. Our faith knows One who unites these diverse characteristics, being God and man, being the Saviour of the body, which is part of Himself and instinct with His life. If we may suppose that He speaks in both verses of the text, then, in the one, as priest and intercessor, He lifts the prayers of earth to heaven in His own holy hands--and in the other, as messenger and Word of God, He brings the answer and command of heaven to earth on His own authoritative lips--thus setting forth the deep mystery of His person and double office as mediator between man and God. But even if we put aside that thought, the correspondence and relation of the two passages remain the same. In any case they are intentionally parallel in form and connected in substance. The latter is the answer to the former. The cry of Zion is responded to by the call of God. The awaking of the arm of the Lord is followed by the awaking of the Church. He puts on strength in clothing us with His might, which becomes ours. The mere juxtaposition of these verses suggests the point of view from which I wish to treat them on this occasion. I hope that the thoughts to which they lead may help to further that quickened earnestness and expectancy of blessing, without which Christian work is a toil and a failure. We have here a common principle underlying both the clauses of our text, to which I must first briefly ask attention, namely-- I. The occurrence in the Church's history of successive periods of energy and of languor. It is freely admitted that such alternation is not the highest ideal of growth, either in the individual or in the community. Our Lord's own parables set forth a more excellent way--the way of uninterrupted increase, whereof the type is the springing corn, which puts forth 'first the blade, then the ear, after that the full corn in the ear,' and passes through all the stages from the tender green spikelets that gleam over the fields in the spring-tide to the yellow abundance of autumn, in one unbroken season of genial months. So would our growth be best, healthiest, happiest. So _might_ our growth be, if the mysterious life in the seed met no checks. But, as a matter of fact, the Church has not thus grown. Rather at the best, its emblem is to be looked for, not in corn, but in the forest tree-the very rings in whose trunk tell of recurring seasons when the sap has risen at the call of spring, and sunk again before the frowns of winter. I have not to do now with the causes of this. These will fall to be considered presently. Nor am I saying that such a manner of growth is inevitable. I am only pointing out a fact, capable of easy verification and familiar to us all. Our years have had summer and winter. The evening and the morning have completed all the days since the first.
