One day all suffering will cease. God promises that He will create a new world where suffering will not exist.
“Then I saw a new heaven and a new earth; for the first heaven and the first earth had passed away, and the sea was no more. 2 I also saw the holy city, the new Jerusalem, coming down out of heaven from God, prepared like a bride adorned for her husband.
3 Then I heard a loud voice from the throne: Look, God’s dwelling is with humanity, and he will live with them. They will be his peoples, and God himself will be with them and will be their God. 4 He will wipe away every tear from their eyes. Death will be no more; grief, crying, and pain will be no more, because the previous things have passed away.” Revelation 21:1-4
