What happens to those who die in their sins according to the Bible?

The Bible indicates that dying in one's sins leads to eternal judgment. In Luke 16:23, we learn about the rich man who, despite his earthly wealth, found himself in torment after death because he rejected Christ. Thus, those who do not come to faith in Christ and remain in their sins will face eternal consequences. The gospel warns that belief in Christ is essential for salvation, clearly stating that the state one dies in reflects their eternal standing—either with Christ or eternally separated from Him.
