By this verse the Prophet teaches, that all the changes of the world depend on celestial motion. For we have said that the living creatures represent to us Angels whom God inspires with a secret virtue, so that he works by means of their hands. Now, therefore, when he says, that the wheels proceeded through a higher movement than their own, it follows that nothing happens by chance in the world, but that God, by his own incomprehensible wisdom, so directs all things that nothing happens except by that secret instinct which is imperceptible to us. Therefore in this teaching of the Prophet, as in a glass, we ought to consider what is concealed from human comprehension. We see many things happen, and in the meantime we think the motions, which are so perplexed and multiplied, confused; but the Prophet meets this perverse imagination, and teaches that the wheels rest by themselves and are set in motion by a higher force -- that is, as the living creatures or cherubim are moved, so the wheels are drawn along by their influence. Now, therefore, because we perceive the meaning of the Holy Spirit, so the usefulness of the doctrine is to be noticed. When we see men planning' so many things that they disturb the whole world, when we see many conspiracies made, and then all things necessary for action prepared, let us perceive that God governs all things, but in a secret manner which surpasses our senses. Also, when we see many things happen as we think unseasonably, let us think that Angels are discharging their duty, and that by their motion and inspiration things in themselves motionless are borne along. The same may be said of other things: winter, for example, may be too mild or too rough; in that excess, let us consider what the Prophet teaches here, viz.: that God so governs the order of the seasons, that nothing happens unless by his inspiration. When, therefore, the living creatures went forward, the wheels near them also wear forward, he says, meaning that the living creatures were the rule by which the wheels directed their course, and when they were raised, he adds, the wheels were raised also.
