What does the Bible say about the judgment after death?

According to Scripture, particularly Hebrews 9:27, it is appointed unto men once to die, but after this the judgment. This refers to the inevitable reality that every individual will face judgment after death, leading to either eternal life or eternal damnation. As illustrated in Luke 16:26, there is a great gulf fixed post-judgment that separates the righteous from the unrighteous, emphasizing the permanence of one's eternal destiny based on the state of their hearts at the time of death. In this context, Christ describes the final separation during the great day of judgment when He sits on His throne, separating His sheep from the goats (Matthew 25:31-46).
