'He shall cover thee with His feathers, and under His wings shalt thou trust: His truth shall be thy shield and buckler.' --PSALM xci. 4.
We remember the magnificent image in Moses' song, of God's protection and guidance as that of the eagle who stirred up his nest, and hovered over the young with his wings, and bore them on his pinions. That passage may possibly have touched the imagination of this psalmist, when he here employs the same general metaphor, but with a distinct and significant difference in its application. In the former image the main idea is that of training and sustaining. Here the main idea is that of protection and fostering. _On_ the wing and _under_ the wing suggest entirely different notions, and both need to be taken into account in order to get the many-sided beauties and promises of these great sayings. Now there seems to me here to be a very distinct triad of thoughts. There is the covering wing; there is the flight to its protection; and there is the warrant for that flight. 'He shall cover thee with His pinions'; that is the divine act. 'Under His wings shalt thou trust'; that is the human condition. 'His truth shall be thy shield and buckler'; that is the divine manifestation which makes the human condition possible.
I. A word then, first, about the covering wing.
Now, the main idea in this image is, as I have suggested, that of the expanded pinion, beneath the shelter of which the callow young lie, and are guarded. Whatever kites may be in the sky, whatever stoats and weasels may be in the hedges, the brood are safe there. The image suggests not only the thought of protection but those of fostering, downy warmth, peaceful proximity to a heart that throbs with parental love, and a multitude of other happy privileges realised by those who nestle beneath that wing. But while these subsidiary ideas are not to be lost sight of, the promise of protection is to be kept prominent, as that chiefly intended by the Psalmist.
This psalm rings throughout with the truth that a man who dwells 'in the secret place of the Most High' has absolute immunity from all sorts of evil; and there are two regions in which that immunity, secured by being under the shadow of the Almighty, is exemplified here. The one is that of outward dangers, the other is that of temptation to sin and of what we may call spiritual foes. Now, these two regions and departments in which the Christian man does realise, in the measure of his faith, the divine protection, exhibit that protection as secured in two entirely different ways.
The triumphant assurances of this psalm, 'There shall no evil befall thee, neither shall any plague come nigh thy dwelling,'--'the pestilence shall smite thousands and ten thousands beside thee, but not come nigh thee,'--seem to be entirely contradicted by experience which testifies that 'there is one event to the evil and the good,' and that, in epidemics or other widespread disasters, we all, the good and the bad, God-fearers and God-blasphemers, do fare alike, and that the conditions of exemption from physical evil are physical and not spiritual. It is of no use trying to persuade ourselves that that is not so. We shall understand God's dealings with us, and get to the very throbbing heart of such promises as these in this psalm far better, if we start from the certainty that whatever it means it does _not_ mean that, with regard to external calamities and disasters, we are going to be God's petted children, or to be saved from the things that fall upon other people. No! no! we have to go a great deal deeper than that. If we have felt a difficulty, as I suppose we all have sometimes, and are ready to say with the half-despondent Psalmist, 'My feet were almost gone, and my steps had well-nigh slipped,' when we see what we think the complicated mysteries of divine providence in this world, we have to come to the belief that the evil that is in the evil will never come near a man sheltered beneath God's wing. The physical external event may be entirely the same to him as to another who is not covered with His feathers. Here are two partners in a business, the one a Christian man, and the other is not. A common disaster overwhelms them. They become bankrupts. Is insolvency the same to the one as it is to the other? Here are two men on board a ship, the one putting his trust in God, the other thinking it all nonsense to trust anything but himself. They are both drowned. Is drowning the same to the two? As their corpses lie side by side among the ooze, with the weeds over them, and the shell-fish at them, you may say of the one, but only of the one, 'There shall no evil befall thee, neither any plague come nigh thy dwelling.'
