Sin is the carrier of death, it was when sin came into the world that was when death also entered. God created human beings to live in fellowship with Him, but when sin came into the world through disobedience, death became part of the human experience. The Bible teaches that physical death is a consequence of living in a fallen world, and it reminds us that our earthly lives are temporary.
Everyone will die one day and the bible gave us hope of eternal life after death. Those who trust in God are promised the hope of resurrection and eternal life through Jesus Christ. Therefore, death is not the end for the faithful but a passage to the fulfillment of God's promise of everlasting life.
