Zechariah 4:12

I have said that there is some difference in the visions though the angel relates hardly anything new, except respecting the flowing and the tubes; but as a new explanation is given, Zechariah no doubt more fully considered what he had slightly looked on before. The more attentive then to the vision the Prophet became, the more confirmed he was; for God showed to him now what he had not sufficiently observed before, namely, that there were pipes or tubes through which the oil flowed into each of the pourers, and further, that these flowing or a continual running of the oil, was like that of a river, which runs through its own channel. But God intended to instruct his Prophet by degrees, that we may learn at this day to apply our thoughts to the understanding of his doctrine; for the instruction to be derived from it is not of an ordinary kind, as I have already reminded you. Indeed the state of things in our time is nearly the same with that of his time: for Christ now renews by the power of his Spirit that spiritual temple which had been pulled down and wholly demolished; for what has been the dignity of the Church for many ages? Doubtless, it has been for a long time in a dilapidated state; and now when God begins to give some hope of a new building, Satan collects together many forces from all parts to prevent the progress of the work. We are also tender and soft, and even faint-hearted, so that hardly one in a hundred labors so courageously as he ought.

We hence then learn how necessary for us is this doctrine: it was not, therefore, to no purpose that the Prophet did not apprehend at once and in an instant what was presented to him in the vision, but made progress by degrees.
