What happens to our body after we die has no moral consequence. So whether we are put six feet under or burned to ashes, it will have no effect one way or the other on what we experience at the resurrection. Having said that, however, the Bible clearly favors burial. In fact, no other option is mentioned. The reason burial was the accepted practice was because the deceased were placed in the ground with the expectation on one day being raised. The practice of cremating the dead began in India among the Hindus, not the Christians or Jews. To me, it seems an awful lot like what will happen to people at the final judgment when they are cast into the laqke of fire. So, not because of any moral concerns but because of the associations, I plan on being buried.
