I once heard through a well known Pastor that we are not to cremate our bodies when we die and I have never found anything in the Bible to confirm that. Could you please share any scriptures to support that or not.
You haven’t found anything in the Bible that prohibits cremation because there isn’t anything.
This is a centuries old man made idea based on the incorrect belief that God cannot resurrect a cremated body.
The truth is, whether a body is cremated or not it soon turns to dust after burial so it makes no difference.
Dead believers get new eternal bodies at the resurrection at the same time the bodies of living believers are made eternal in the rapture. (1 Corinthians 15:52-53).
