The Bible does not explicitly address the morality of cremation. On certain occasions recorded in the Old Testament, burning a body was done as an act of disrespect and judgment upon the deceased (Joshua 7:25, 2 Kings 23:20). On other occasions, bodies were cremated as a way of honoring the dead (1 Samuel 31:11-13).

Traditionally, cremation was not practiced in the early church because of the sanctity that biblical teaching places on the human body, such as a belief in the bodily resurrection of the dead (1 Corinthians 15:50-58). Some choose to avoid cremation as an expression of their anticipation of this bodily resurrection. Others understand that God can resurrect a body from ashes or other remains, pointing to Revelation 20:13 where it explicitly states that God raised up those who had died at sea. In a scientific sense, cremation just speeds up the natural process that eventually disintegrates the body after death. It will be no hindrance to God in the resurrection if one has been cremated. The family should consider their own feelings about burial and cremation, and do what they are comfortable with. It is not a sin.
