Shall thy wonders be known in the dark? - In the dark world; in "the land of darkness and the shadow of death; a land of darkness, as darkness itself, and where the light is as darkness." Job 10:21-22. "And thy righteousness." The justice of thy character; or, the ways in which thou dost maintain and manifest thy righteous character.

In the land of forgetfulness - Of oblivion; where the memory has decayed, and where the remembrance of former things is blotted out. This is a part of the general description, illustrating the ideas then entertained of the state of the dead; that they would be weak and feeble; that they could see nothing; that even the memory would fail, and the recollection of former things pass from the mind. All these are images of the grave as it appears to man when he has not the clear and full light of revelation; and the grave is all this - a dark and cheerless abode - all abode of fearfulness and gloom - when the light of the great truths of the Gospel is not suffered to fall upon it. That the psalmist dreaded this is clear, for he had not yet the full light of revealed truth in regard to the grave, and it seemed to him to be a gloomy abode. That people without the Gospel ought to dread it, is clear, for when the grave is not illuminated with Christian truth and hope, it is a place from which man by nature shrinks back, and it is not wonderful that a wicked man dreads to die.

The land of forgetfulness? - The place of separate spirits, or the invisible world. The heathens had some notion of this state. They feigned a river in the invisible world, called Lethe, Ληθη, which signifies oblivion, and that those who drank of it remembered no more any thing relative to their former state.

- Animae, quibus altera fato

Corpora debentur, lethaei ad fluminis undam

Securos latices et longa oblivia potant.

Virg. Aen. 6: 713.

To all those souls who round the river wait

New mortal bodies are decreed by fate;

To yon dark stream the gliding ghosts repair,

And quaff deep draughts of long oblivion there.

Shall thy wonders be known in the dark?.... A description of the grave again; see Job 10:21, The sense may be, should he continue in the dark and silent grave, how would the wonders of the grace of God, of electing, redeeming, justifying, pardoning, and adopting grace, be made known; the wonders of Christ's person and offices, and the wondrous things, and doctrines of the Gospel, relating thereunto? as the glory of these would be eclipsed, there would be none to publish them:

and thy righteousness in the land of forgetfulness? the grave, where the dead lie, who, having lost all sense of things, forget what were done in this world, and they themselves are quickly forgotten by the living; and had Christ continued in this state, and had not risen again to our justification, how would his justifying righteousness have been revealed, as it is from faith to faith in the Gospel, which is therefore called the word and ministration of righteousness?

Shall thy wonders be known in the dark? and thy righteousness in the land {k} of forgetfulness?

(k) That is, in the grave, where only the body lies without all sense and remembrance.

88:12 Forgetfulness - In the grave, where men are forgotten by their nearest relations.

88:10-18 Departed souls may declare God's faithfulness, justice, and lovingkindness; but deceased bodies can neither receive God's favours in comfort, nor return them in praise. The psalmist resolved to continue in prayer, and the more so, because deliverance did not come speedily. Though our prayers are not soon answered, yet we must not give over praying. The greater our troubles, the more earnest and serious we should be in prayer. Nothing grieves a child of God so much as losing sight of him; nor is there any thing he so much dreads as God's casting off his soul. If the sun be clouded, that darkens the earth; but if the sun should leave the earth, what a dungeon would it be! Even those designed for God's favours, may for a time suffer his terrors. See how deep those terrors wounded the psalmist. If friends are put far from us by providences, or death, we have reason to look upon it as affliction. Such was the calamitous state of a good man. But the pleas here used were peculiarly suited to Christ. And we are not to think that the holy Jesus suffered for us only at Gethsemane and on Calvary. His whole life was labour and sorrow; he was afflicted as never man was, from his youth up. He was prepared for that death of which he tasted through life. No man could share in the sufferings by which other men were to be redeemed. All forsook him, and fled. Oftentimes, blessed Jesus, do we forsake thee; but do not forsake us, O take not thy Holy Spirit from us.
