Question: Will the redeemed still be happy in heaven when they remember their lost loved ones?
Answer: Some believe that they can not enjoy the pleasures of heaven because their lost loved ones are suffering in the eternal hell. But the Bible teaches that hell is not forever. The fire of hell will certainly go out once it accomplishes its purpose of judgement to each person according to his works. There will be a brief period of sorrow but after the fire goes out, the Lord will comfort His children. For more on that topic, check the following link: https://bibleask.org/is-hell-forever/
The Bible says that God will “wipe away all tears from their eyes” (Rev. 21:4). Death is swallowed up in victory (1 Cor. 15:54); “The last enemy that shall be destroyed is death” (v. 26). Much of life’s misery and anguish is the result of harassing pain. Pain will be completely banished in that beautiful world of tomorrow.
Surrounded by the beauty and joys of the new earth, God’s redeemed will forget the past; “the former shall not be remembered, nor come into mind” (Isa. 65:17). The former would include the “former troubles” (v. 16), and the hardships of this present evil world. The peace and glory of the new earth will so far transcend the trouble and woe of this present world that the trials will seem like nothing in comparison (Jer. 3:16; Isa. 43:18, 19).
The memory of former things will no longer distress or annoy the redeemed or cause feelings of remorse. In that world of tomorrow all the perplexities of life’s experiences will simply vanish. When the redeemed will no longer “see through a glass, darkly” (1 Cor. 13:12) they shall have a “distinct, intelligent knowledge” of what their salvation has cost. And they will rejoice in God’s infinite love. “And the ransomed of the LORD shall return, and come to Zion with songs and everlasting joy upon their heads: they shall obtain joy and gladness, and sorrow and sighing shall flee away” (Isa. 35:10).
