I'm specifically talking about the following passages:
“What profit is there in my death, if I go down to the pit? Will the dust praise you? Will it tell of your faithfulness? [Psalm 30:9 ESV]
4 Turn, O Lord, deliver my life; save me for the sake of your steadfast love. 5 For in death there is no remembrance of you; in Sheol who will give you praise? [Psalm 6:4-5 ESV]
17 The dead do not praise the Lord, nor do any who go down into silence. [Psalm 115:17 ESV]
10 Do you work wonders for the dead?
Do the departed rise up to praise you? Selah
11 Is your steadfast love declared in the grave,
or your faithfulness in Abaddon?
12 Are your wonders known in the darkness,
or your righteousness in the land of forgetfulness?
[Psalm 88:10-12 ESV]
9 Sheol beneath is stirred up to meet you when you come; it rouses the shades to greet you, all who were leaders of the earth; it raises from their thrones all who were kings of the nations. 10 All of them will answer and say to you: ‘You too have become as weak as we! You have become like us!’ 11 Your pomp is brought down to Sheol, the sound of your harps; maggots are laid as a bed beneath you, and worms are your covers.
[Isaiah 14:9-11 ESV]
17 Behold, it was for my welfare that I had great bitterness; but in love you have delivered my life from the pit of destruction, for you have cast all my sins behind your back. 18 For Sheol does not thank you; death does not praise you; those who go down to the pit do not hope for your faithfulness. 19 The living, the living, he thanks you, as I do this day; the father makes known to the children your faithfulness.
[Isaiah 38:17-19 ESV]
10 But a man dies and is laid low; man breathes his last, and where is he? 11 As waters fail from a lake and a river wastes away and dries up, 12 so a man lies down and rises not again; till the heavens are no more he will not awake or be roused out of his sleep. [Job 14:10-12 ESV]
13 If I hope for Sheol as my house, if I make my bed in darkness, 14 if I say to the pit, ‘You are my father,’ and to the worm, ‘My mother,’ or ‘My sister,’ 15 where then is my hope? Who will see my hope? 16 Will it go down to the bars of Sheol? Shall we descend together into the dust?” [Job 17:13-16 ESV]
18 “Why did you bring me out from the womb? Would that I had died before any eye had seen me 19 and were as though I had not been, carried from the womb to the grave. 20 Are not my days few? Then cease, and leave me alone, that I may find a little cheer 21 before I go—and I shall not return— to the land of darkness and deep shadow, 22 the land of gloom like thick darkness, like deep shadow without any order, where light is as thick darkness.”
[Job 10:21-22 ESV]
At face value, it looks like neither David nor Isaiah nor Job believed they would be in paradise, in the presence of God, where they would be able to worship Him and praise Him, as soon as they died. Nor did they seem to have expected to enter into any sort of blissful state. Instead, they refer to death in pessimistic terms, such as silence, darkness, forgetfulness, destruction (other translations say oblivion or nothingness), sleep, worms, maggots, weak, dust, "bars of Sheol", devoid of praise, devoid of hope, etc.
In fact, we find similar pessimistic language in Ecclesiastes chapter 9:
5 For the living know that they will die, but the dead know nothing, and they have no more reward, for the memory of them is forgotten. 6 Their love and their hate and their envy have already perished, and forever they have no more share in all that is done under the sun. [ESV]
10 Whatever your hand finds to do, do it with your might, for there is no work or thought or knowledge or wisdom in Sheol, to which you are going. [ESV]
Question: How do Christians who believe that the saints enter a blissful state as soon as they die explain David, Isaiah & Job's pessimistic outlook on death?
