That’s not what Jesus teaches about the value of our bodies, and the duty for reverence towards the dead and human remains.
Again, cremation is what the pagans did to their dead. Christians have always buried or preserved them in some way or shape or form, *because* we believe in bodily resurrection.
Jesus has let us all know that nothing this side of heaven is going to get in the way of His taking us to be with Him.
Our body is valuable only until we are done with it..then frankly it rots....He wants us to value “life” and what we do with our bodies while we are in it.
After death...You can dress it, burn it, put it in a coffin, dump it in the sea, cremate it or whatever....it’s still a dead body...useless. It has served it’s earthly purpose.
