(4.) Their motions. The living creatures are moving. Angels are active beings; it is not their happiness to sit still and do nothing, but to be always well employed; and we must reckon ourselves then best when we are doing good, doing it as the angels do it, or whom it is here observed, [1.] That whatever service they went about they went every one straight forward (v. 9, 12), which intimates, First, That they sincerely aimed at the glory of God, and had a single eye to that, in all they did. Their going straight forward supposes that they looked straight forward, and never had any sinister intentions in what they did. And, if thus our eye be single, our whole body will be full of light. The singleness of the eye is the sincerity of the heart. Secondly, That they were intent upon the service they were employed in, and did it with a close application of mind. They went forward with their work; for what their hand found to do they did with all their might and did not loiter in it. Thirdly, That they were unanimous in it: They went straight forward, every one about his own work; they did not thwart or jostle one another, did not stand in one another's light, in one another's way. Fourthly, That they perfectly understood their business, and were thoroughly apprised of it, so that they needed not to stand still, to pause of hesitate, but pursue their work with readiness, as those that knew what they had to do and how to do it. Fifthly, They were steady and constant in their work. They did not fluctuate, did not tire, did not vary, but were of a piece with themselves. They moved in a direct line, and so went the nearest way to work in all they did and lost no time. When we go straight we go forward; when we serve God with one heart we rid ground, we rid work. [2.] They turned not when they went, v. 9, 12. First, They made no blunders or mistakes, which would give them occasion to turn back to rectify them; their work needed no correction, and therefore needed not to be gone over again. Secondly, They minded no diversions; as they turned not back, so they turned not aside, to trifle with any thing that was foreign to their business. [3.] They went whither the Spirit was to go (v. 12), either, First, Whither their own spirit was disposed to go; thither they went, having no bodies, as we have, to clog or hinder them. It is our infelicity and daily burden that, when the spirit if willing, yet the flesh is weak and cannot keep pace with it, so that the good which we would do we do it not; but angels and glorified saints labour under no such impotency; whatever they incline or intend to do they do it, and never come short of it. Or, rather, Secondly, Whithersoever the Spirit of God would have them go, thither they went. Though they had so much wisdom of their own, yet in all their motions and actions they subjected themselves to the guidance and government of the divine will. Whithersoever the divine Providence was to go they went, to serve its purposes and to execute its orders. The Spirit of God (says Mr. Greenhill) is the great agent that sets angels to work, and it is their honour that they are led, they are easily led, by the Spirit. See how tractable and obsequious these noble creatures are. Whithersoever the Spirit is to go they go immediately, with all possible alacrity. Note, Those that walk after the Spirit do the will of God as the angels do it. [4.] They ran and returned like a flash of lightning, v. 14. This intimates, First, That they made haste; they were quick in their motions, as quick as lightning. Whatever business they went about they despatched it immediately, in a moment, in the twinkling of an eye. Happy they that have no bodies to retard their motion in holy exercises. And happy shall we be when we come to have spiritual bodies for spiritual work. Satan falls like lightning into his own ruin, Luke x. 18. Angels fly like lightning in their Master's work. The angel Gabriel flew swiftly. Secondly, That they made haste back: They ran and returned; ran to do their work and execute their orders, and then returned to give an account of what they had done and receive new instructions, that they might be always doing. They ran into the lower world, to do what was to be done there; but, when they had done it, they returned like flash of lightning to the upper world again, to the beatific vision of their God, which they could not with any patience be longer from than their service did require. Thus we should be in the affairs of this world as out of our element. Though we run into them, we must not repose in them, but our souls must quickly return like lightning to God their rest and centre.
