His disciples remembered that it was written, "Zeal for your house will eat me up."
Accordingly, the Evangelist says, that this was one of the marks by which the disciples knew that it was Jesus who protected and restored the kingdom of God. Now observe that they followed the guidance of Scripture, in order to form such an opinion concerning Christ as they ought to entertain; and, indeed, no man will ever learn what Christ is, or the object of what he did and suffered, unless he has been taught and guided by Scripture. So far, then, as each of us shall desire to make progress in the knowledge of Christ, it will be necessary that Scripture shall be the subject of our diligent and constant meditation. Igor is it without a good reason that David mentions the house of God, when the divine glory is concerned; for though God is sufficient for himself, and needs not the services of any, yet he wishes that his glory should be displayed in the Church. In this way he gives a remarkable proof of his love towards us, because he unites his glory — as it were, by an indissoluble link — with our salvation.
