It seems that your specific grievance is due to unhealed illness, specifically of your wife's. I found
an article that specifically deals on that issue, and I hope this could help.
Throughout the Bible, we are constantly reminded that this life isn't all there is: Everything in this world will pass away, but God's word endures forever (1 Peter 24-35; 1 John 2:16-17). We are of God's Kingdom, and His Kingdom is not of this present world (John 17:16; John 18:35), and He has promised to prepare a place for us in His father's house, where the joy and glory we will receive shall outweigh all our present suffering (John 14: 2-3; Romans 8:18).
Questioning Brother said:
Yet he lost what was most important: his kids. New ones would not have replaced the ones killed. At that point, Job’s wife would not have had to say to me, “curse God and die.” Pain will not drive Me to him for anything but relief. It will not increase love, trust, or anything like that.
He has not lost them, though, at least not permanently. That is why, at the end of his story, Job regained everything he had lost twice-fold, except for children, which he gets in the same number as he originally had (seven sons and three daughters). Commentators have remarked that this is an assurance that he will eventually reunite with the children he lost, and with the ten children he had after God restored him, he will then have twice as many children as he did before. Job himself clearly believe in the resurrection of the dead, or at least have some idea of the afterlife (
Job 19:25–27), and 1 Corinthians 15 assures us that we do not need to fear or lose hope over sickness and death:
52 in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed.
53 For the perishable must clothe itself with the imperishable, and the mortal with immortality.
54 When the perishable has been clothed with the imperishable, and the mortal with immortality, then the saying that is written will come true: “Death has been swallowed up in victory.”
55 “Where, O death, is your victory?
Where, O death, is your sting?”
56 The sting of death is sin, and the power of sin is the law.
57 But thanks be to God! He gives us the victory through our Lord Jesus Christ.
58 Therefore, my dear brothers and sisters, stand firm. Let nothing move you. Always give yourselves fully to the work of the Lord, because you know that your labor in the Lord is not in vain.
Now, I understand that it's difficult to see a loved one suffer in illness, and I hope your wife could recover. But no matter what happens, you can be sure that, in Christ, she will one day be raised more beautiful and perfect than she ever has been. That is what God had promised.
