My personal faith in Jesus Christ as my Lord and Savior causes me to look at my body, after death, from a biblical perspective.
The same thing happens to every body, eventually...
"Then shall the dust return to the earth as it was; and the spirit shall return to God who gave it.”
Ecclesiastes 12:7
So if this body is basically trash, waiting to return to dust (which obviously happens whether the body is burnt, buried, blown apart, left to rot and be scavenged, tossed in the sea, etc.), then I see no reason to give it special treatment... Especially embalming it and placing it in an expensive box, and then vaulted in the Earth!
Probably cremation, it's cheap. Or, if I'm fortunate enough to die here in this old Kentucky home, there is an old cemetery up on the hill on our property. The most recent headstone reads died in 1905. Perhaps a pine box and a simple stone up there.
I do know this, now that I'm 46, and starting to feel all of the misuse and overuse I've done with this body, I'm very much looking forward to the one that I have coming...
"For we know that when this earthly tent we live in is taken down (that is, when we die and leave this earthly body), we will have a house in heaven, an eternal body made for us by God himself and not by human hands. We grow weary in our present bodies, and we long to put on our heavenly bodies like new clothing. For we will put on heavenly bodies; we will not be spirits without bodies. While we live in these earthly bodies, we groan and sigh, but it’s not that we want to die and get rid of these bodies that clothe us. Rather, we want to put on our new bodies so that these dying bodies will be swallowed up by life. God himself has prepared us for this, and as a guarantee he has given us his Holy Spirit. So we are always confident, even though we know that as long as we live in these bodies we are not at home with the Lord."
2 Cor 5:1-6
