Interesting question, isn’t it? I was asked that question a few days ago, and I pointed the person to one verse and then made one observation (just a summary of our discussion!). The practice of cremation is not specifically mentioned in the Bible. However, a section in the Bible that talks about how a Christian’s “eternal” body will be different than his/her “physical” body is 1 Corinthians 15:42-44 (make sure you read it in context). The eternal does not seem to be limited by the physical. Also, the physical body starts to decay the moment the person dies, so whether the process takes a few minutes (eg, cremation) or a few years (eg, burial), the end result would seem to be the same, wouldn’t it?
What do think about cremation?
