Is it wrong for a born-again, spirit filled Christian to be cremated?
While it is probably not unethical for a Christian to be cremated, some Christians have strong reservations about it because it involves a living person choosing to have their own body immolated or destroyed, rather than simply allowed to decay in the earth. To some, this suggests a denial of God’s right to determine the end of our life and our life processes. Still others object because of the Christian belief in the resurrection of the body or in the body, which is promised in scripture (see 1 Corinthians 15).
