It is expressive of deep truth that first in order is named, as the cause of success, 'the prophesying of Haggai and Zechariah.' 'Practical men,' no doubt, then as always, set little store by the two prophets' fiery words, and thought that a couple of masons would have done more for the building than they did. The contempt for 'ideas' is the mark of shallow and vulgar minds. Nothing is more practical than principles and motives which underlie and inform work, and these two prophets did more for building the Temple by their words than an army of labourers with their hands. 'There are diversities of operations,' and it is not given to every man to handle a trowel; but no good work will be prosperously accomplished unless there be engaged in it prophets who rouse and rebuke and hearten, and toilers who by their words are encouraged and saved from forgetting the sacred motives and great ends of their work in the monotony and multiplicity of details. Still more important is the next point mentioned. The work was done 'according to the commandment of the God of Israel.' There is peculiar beauty and pathos in that name, which is common in Ezra. It speaks of the sense of unity in the nation, though but a fragment of it had come back. There was still an Israel, after all the dreary years, and in spite of present separation. God was still its God, though He had hidden His face for so long. An inextinguishable faith, wistful but assured, in His unalterable promise, throbs in that name, so little warranted by a superficial view of circumstances, but so amply vindicated by a deeper insight. His 'commandment' is at once the warrant and the standard for the work of building. In His service we are to be sure that He bids, and then to carry out His will whoever opposes. We are to make certain that our building is 'according to the pattern showed in the mount,' and, if so, to stick to it in every point. There is no room for more than one architect in rearing the temple. The working drawings must come from Him. We are only His workmen. And though we may know no more of the general plan of the structure than the day-labourer who carries a hod does, we must be sure that we have His orders for our little bit of work, and then we may be at rest even while we toil. They who build according to His commandment build for eternity, and their work shall stand the trial by fire. That motive turns what without it were but 'wood, hay, stubble,' into 'gold and silver and precious stones.'
