Cremation has become a very popular choice for dealing with our earthly remains. There are a variety of reasons why people choose cremation: cost, use of space, even environmental reasons. In the past, pastors spoke against cremation. Why? Is it a biblically acceptable choice?
The first thing to consider is the Bible’s teaching about the resurrection of our bodies. At Judgment Day all people, both saved and not, are to be raised in a physically imperishable form. (For one of many articles on this topic see the following) https://wordpress.com/post/afterdeathsite.com/825 This will be good news for those who have a part in God’s New Heaven and New Earth. It will not be so great for those who will be forsaken by God. (Use the search bar for more on all of these topics)
In the past, it was common for people to be cremated either in an attempt to stop their own resurrection or to make a statement that they didn’t believe in a resurrection. In such a context, cremation was unacceptable. That is typically not the motive today.
Another objection sometimes raised against cremation is that the Jews buried their dead and pagans burned their dead. In the case of paganism and Eastern religions, cremation did have a theological significance. These religions saw the body as something evil. Our goal was to be free of the body. Burning the body liberated the soul. Conversely, burying the body had a theological foundation that acknowledged that our body, even after death, was a part of us. We are not a soul renting a body. We are body and soul.
That said, there is no laws against cremation in the Bible. Having examples like that stated above do not create unwritten rules. God has no problem resurrecting a person regardless of how their body was disposed. It is not a given that He will use the very same molecules. You will get a body that is uniquely you that is appropriate for the New Earth or Gehenna.
Cremation sometimes can have a positive or negative psychological effect on a person before they die. Some are distressed by the thought of their bodies burning. Others are distressed at their bodies decaying or being eaten. Both are unnecessary concerns, because you will be unconnected and unaware at the time.
Scattering of ashes in a favorite place is a common practice. This too finds its origin in the idea being freed from the body. It is not the greatest witness but few think of the theological origins of such a practice.
There is nothing wrong with saving money. Nor is there anything wrong with being mindful of space or ecology. I would conclude that there is nothing wrong with cremation if that is your preference and not distressing for your relatives.
God is able to take you to the next step no matter what you do. He can even resurrect ashes flung to the wind.
