Death

Death entered the world through sin (Romans 5:12). The Bible treats death as an enemy, not a natural part of God's design. Physical death separates body from soul. Spiritual death separates the soul from God. The 'second death' (Revelation 20:14) is eternal separation. But the gospel's whole point is that Jesus conquered death through His resurrection. 'O death, where is your sting?' (1 Corinthians 15:55). Death is real, but it doesn't get the last word.
