Ezekiel 1:15 - Wesley's Explanatory Notes

Living creatures — By each of the living creatures stood one wheel, so that they were four in number, according to the number of living creatures. Four faces — By this it appears, each wheel had its four faces. While he was contemplating the glory of the former vision, this other was presented to him: wherein the dispensations of providence are compared to the wheels of a machine, which all contribute to the regular motion of it. Providence orders, changes: sometimes one spoke of the wheel is uppermost, sometimes another. But the motion of the wheel on its own axle — tree, is still regular and steady. And the wheel is said to be by the living creatures, who attend to direct its motion. For all inferior creatures are, and move, and act, as the Creator, by the ministration of angels directs and influences them: visible effects are managed and governed by invisible causes.
