Calvin on the Protection God provides for His Children through Angels

(Taken from Institutes of the Christian Religion Ch. 14)

As the refulgence of the Divine glory is manifested in them, there is nothing to which we are more prone than to prostrate ourselves before them in stupid adoration, and then ascribe to them the blessings which we owe to God alone. Even John confesses in the Apocalypse (Rev. 19:10; 22:8, 9), that this was his own case, but he immediately adds the answer which was given to him, “See thou do it not; I am thy fellow servant: worship God.”

This danger we will happily avoid, if we consider why it is that Gods instead of acting directly without their agency, is wont to employ it in manifesting his power, providing for the safety of his people, and imparting the gifts of his beneficence. This he certainly does not from necessity, as if he were unable to dispense with them. Whenever he pleases, he passes them by, and performs his own work by a single nod: so far are they from relieving him of any difficulty. Therefore, when he employs them it is as a help to our weakness, that nothing may be wanting to elevate our hopes or strengthen our confidence. It ought, indeed, to be sufficient for us that the Lord declares himself to be our protector. But when we see ourselves beset by so many perils, so many injuries, so many kinds of enemies, such is our frailty and effeminacy, that we might at times be filled with alarm, or driven to despair, did not the Lord proclaim his gracious presence by some means in accordance with our feeble capacities. For this reason, he not only promises to take care of us, but assures us that he has numberless attendants, to whom he has committed the charge of our safety, that whatever dangers may impend, so long as we are encircled by their protection and guardianship, we are placed beyond all hazard of evil. I admit that after we have a simple assurance of the divine protection, it is improper in us still to look round for help. But since for this our weakness the Lord is pleased, in his infinite goodness and indulgence, to provide, it would ill become us to overlook the favour. Of this we have an example in the servant of Elisha (2 Kings 6:17), who, seeing the mountain encompassed by the army of the Assyrians, and no means of escape, was completely overcome with terror, and thought it all over with himself and his master. Then Elisha prayed to God to open the eyes of the servant, who forthwith beheld the mountain filled with horses and chariots of fire; in other words, with a multitude of angels, to whom he and the prophet had been given in charge. Confirmed by the vision he received courage, and could boldly defy the enemy, whose appearance previously filled him with dismay.
