How did death become an enemy according to the Bible?

Death is described as an enemy in Scripture, particularly in 1 Corinthians 15:26, where Paul states that the last enemy to be destroyed is death. This culminated from the fall of Adam in the Garden of Eden, where sin entered the world through disobedience. According to Genesis, God warned Adam that eating from the tree of knowledge would result in death. In this sense, death can be seen as an enemy because it is the consequence of sin. However, through Christ’s sacrificial death and resurrection, He has conquered death, transforming it from an ultimate enemy into a passage for believers to eternal life. Thus, while death is a reality in a fallen world, for Christians, the fear of death has been defeated through Christ’s victory.
