But faith finds a path where speculation discerns none. The psalmist "went into the sanctuary (literally, sanctuaries) of God," and there light streamed in on him, in which he saw light. Not mere entrance into the place of worship, but closer approach to the God who dwelt there, cleared away the mists. Communion with God solves many problems which thinking leaves unresolved. The eye which has gazed on God is purged for much vision besides. The disproportion between the deserts and fortunes of good and bad men assumes an altogether different aspect when contemplated in the light of present communion with Him, which brings a blessedness that makes earthly prosperity seem dross, and earthly burdens seem feathers. Such communion, in its seclusion from worldly agitations, enables a man to take calmer, saner views of life, and in its enduring blessedness reveals more clearly the transiency of the creatural good which deceives men with the figment of its permanence. The lesson which the psalmist learned in the solemn stillness of the sanctuary was the end of ungodly prosperity. That changes the aspect of the envied position of the prosperous sinner, for his very prosperity is seen to contribute to his downfall, as well as to make that downfall more tragic by contrast. His sure footing, exempt as he seemed from the troubles and ills that flesh is heir to, was really on a treacherous slope, like smooth sheets of rock on a mountain-side. To stand on them is to slide down to hideous ruin.
The theme of the end of the prosperous sinners is continued in the next group (vv. 19-22). In ver. 19 the psalmist seems as if standing an amazed spectator of the crash, which tumbles into chaos the solid-seeming fabric of their insolent prosperity. An exclamation breaks from his lips as he looks. And then destruction is foretold for all such, under the solemn and magnificent image of ver. 20. God has seemed to sleep, letting evil run its course; but He "rouses Himself"--that is, comes forth in judicial acts--and as a dreamer remembers his dream, which seemed so real, and smiles at its imaginary terrors or joys, so He will "despise" them, as no more solid nor lasting than phantasms of the night. The end contemplated by the psalmist is not necessarily death, but any sudden overthrow, of which there are many in the experience of the godless. Life is full of such awakings of God, both in regard to individuals and nations, which, if a man duly regards, he will find the problem of the psalm less insoluble than at first it appears. But if there are lives which, being without goodness, are also without chastisement, Death comes at last to such as God's awaking, and a very awful dissipating of earthly prosperity into a shadowy nothing.
The psalmist has no revelation here of future retribution. His vindication of God's justice is not based on that, but simply on the transiency of worldly prosperity, and on its dangerous character. It is "a slippery place," and it is sure to come to an end. It is obvious that there are many other considerations which have to be taken into account, in order to a complete solution of the problem of the psalm. But the psalmist's solution goes far to lighten the painful perplexity of it; and if we add his succeeding thoughts as to the elements of true blessedness, we have solution enough for peaceful acquiescence, if not for entire understanding. The psalmist's way of finding an answer is even more valuable than the answer which he found. They who dwell in the secret place of the Most High can look on the riddle of this painful world with equanimity, and be content to leave it half unsolved.
Vv. 21, 22, are generally taken as one sentence, and translated as by Delitzsch, "If my heart should grow bitter ... I should be brutish," etc.; or, as by Hupfeld, "When my heart grew bitter ... then I was as a beast," etc.; but they are better regarded as the psalmist's penitent explanation of his struggle. "Unbelieving thoughts had fermented in his mind, and a pang of passionate discontent had pierced his inmost being. But the higher self blames the lower self for such folly" (Cheyne, _in loc._). His recognition that his doubts had their source, not in defect in God's providence, but in his own ignorance and hasty irritation, which took offence without cause, prepares him for the sweet, clear note of purely spiritual aspiration and fruition which follows in the next strophe.
