Some Christians are afraid of cremation of their bodies, because them in some way are afraid or suspect that cremation may harm their resurrection.
What does Bible say on cremation? It seems that Bible suggests that cremation is a good thing for a believer:
… if I give my body to be burned, but don’t have love, it profits me nothing.
It seems from this verse that body being burned may “profit” something.
Maybe resurrecting a cremated body gives greater glory to God in resurrecting? I don’t know for sure, I just say my opinion.
