No Obstacle to Resurrection
The Bible clearly teaches that Jehovah God will bring back to life many who now sleep in death. (Ecclesiastes 9:5, 10; John 5:28, 29) Prophetically describing the time when the dead will return to life, the Bible book of Revelation, or Apocalypse, says: “The sea gave up those dead in it, and death and Hades gave up those dead in them.” (Revelation 20:13) To accomplish this, it makes no difference to Almighty God whether a person’s body is buried, burned, lost at sea, eaten by wild animals, or even vaporized by an atomic explosion.
The Bible gives no specific direction concerning what ought to be done with the bodies of the dead. Cremation is not condemned by Jehovah. Clearly, though, funeral arrangements should be dignified and respectful.
Something that might influence a person’s decisions in making these arrangements, however, is the way that the local community views funeral customs. Those who abide by Bible principles would certainly not want to do anything that would cause unnecessary offense to their neighbors. It would also be inappropriate to engage in a practice that might seem to indicate belief in false religious teachings, such as the immortality of the soul. These concerns aside, whatever decision a person might make as to how his own body, or that of another, is to be disposed of is really a personal or family matter.
