The disobedience of human to God in the beginning of life was what brought death into this world, and since then everyone now have to die one day. From that time, all people became subject to death because of the effects of sin. It reminds us that physical death is a reality everyone faces and shows the seriousness of turning away from God's will.
The bible also gave us hope that one day everything will be fine. It teaches that those who remain faithful to God have the promise of eternal life. Although death is part of our present human experience, believers can look forward to a future where death will no longer exist and God's people will live with Him forever.
