What does the Bible say about death and eternity?

The Scriptures clearly convey that death is a universal experience for all humanity, with Ecclesiastes 3:20 declaring, 'All go to the same place; all come from dust, and to dust all return.' This profound truth emphasizes the impartiality of death, leveling all distinctions among people. As Spurgeon illustrates, regardless of social status or earthly achievements, we all face the grave without exception. In addition, Psalm 90:5-6 poignantly reminds us of the fleeting nature of life compared to eternity, as it states, 'You sweep men away in the sleep of death; they are like the new grass of the morning.' Our time on earth is short, leading to the inevitability of our eternal existence, either in communion with God or separated from Him.
